Lathliss, Dragon QueenLathliss, Dragon Queen

While Lathliss costs a whopping six mana, a couple of things to take into account: red has a much easier time ramping these days (more on that later), and we're getting what we paid for here. Each nontoken Dragon that enters begets us an additional 5/5 Dragon token. Then, for two mana, we can pump all of those flying lizards a smidge for a turn, and we can do this repeatedly if needed. Her 6/6 stat line is nothing to sneeze at, either, and she gets affected by her own ability. This will be useful if commander damage is the plan when someone gains an insurmountable amount of life.

While there are cheaper options for a Mono-Red Dragon deck out in the wild, Lathliss is certainly not the weakest, nor does she disappoint. In fact, she's the most popular option out there, and for good reason. Also, now would be a good time for me to say it's best to assume each Dragon we talk about has flying unless I say otherwise (this need not apply to non-Dragons, of which there are several).

• Chandra's IgnitionChandra's Ignition: One of red's best board wipes. Ideally, we want to be choosing a creature we control with the highest power. Not only does it clear the board, it also deals a great amount of damage to our opponents. Note two things: this will do nothing (fizzle) if our target's removed, and this will affect our creatures, too.
• Utvara HellkiteUtvara Hellkite: One of, if not, the most expensive cards in our deck, and what we're getting is real nasty. For each Dragon we attack with, we get a 6/6 Dragon token. The more Dragons we swing with, the more tokens we get. Yes, those tokens you make will count, too. Unchecked, this will spiral out of control.
• Goldlust TriadGoldlust Triad: When we attack, we get a token copy going at each of our other opponents. Yes, this will mean that we get up to three Treasure tokens, which will go a long way to help us cast our Dragons. It reminds me of Goldspan DragonGoldspan Dragon, which (spoilers) I'll get to soon.
• Dragonhawk, Fate's TempestDragonhawk, Fate's Tempest: This is a fun one. Its trigger reads like a novel, but here's the short of it: when it enters or attacks, we exile cards from the top of our library for each creature that's power 4 or greater (like a lot of our Dragons). Then, we can either play those cards, or let them go for the rest of the game. If we pick the latter, Hawky over here will deal two damage for each card you leave behind to each opponent at the end of our turn.
• Dragon TempestDragon Tempest: With each Dragon we cast, it gains haste for the turn, meaning we can attack the turn it enters. It also removes a blocker or pings an opponent for damage equal to the number of Dragons we control. All these for the small price of two mana.

The game plan here is very simple: We ramp hard, start running out our Dragons, then proceed to scorch our opponents' life totals. Seriously, it's as simple as it gets. As I'll get to at the end, it's a very easy deck to pilot, and it's great if you want to pilot such a deck.

• Dragonlord's ServantDragonlord's Servant: This and Dragonspeaker ShamanDragonspeaker Shaman both come down early to reduce the costs of our Dragons. That said, they are creatures, so they'll be very prone to removal. But, get them to stick, and we can drop our big threats (including our commander) earlier than normal. Since Dragons tend to be expensive, you want to be ramping as much as you can early on.
• Unexpected WindfallUnexpected Windfall: Speaking of ramping, Treasures are another avenue to ramp. Each token can only be used once, so spend them wisely. We need to discard a card, but we can send any excess lands (or some creatures, like one I'll cover in a moment) to the graveyard, and we get two cards on top of the Treasures.
• Scourge of the ThroneScourge of the Throne: One of our finishers in the deck, and the extra combat step we get helps with this. Like I said, the game plan late in the game is to drop big threats and swing for the fences. With this particular Dragon, we need to attack an opponent with the highest life total, so we can attack again. Note that, if we're at the highest, then the ability won't trigger.

As to be expected from precons slated for newer players, there's no real combo here. Don't we love it when less is more? There's beauty in simplicity, after all. And our "simplicity" comes from some neat synergies.

• AngerAnger: This is actually not a creature that should be cast, but instead put into our graveyard. One way to do this is by discarding it (you know, Unexpected WindfallUnexpected Windfall), so then we can get the effect right away and we saved four mana and some time trying to get it killed. There are a few ways to discard it in the deck, so be on the look out for those.
• Basilisk CollarBasilisk Collar: This piece of equipment might seem a random include, but while the lifelink can help keep us in the game, it's the deathtouch where we get to do some devious tricks. Place this on a much smaller creature, then target it with Chandra's IgnitionChandra's Ignition to effectively clear the board (except for indestructible creatures). One damage makes all the difference. On the other hand, we can equip it to a larger creature, cast the Ignition, and gain a ton of life instead. Both are good.
• Scourge of ValkasScourge of Valkas: Both this and Dragon TempestDragon Tempest work in tandem with Utvara HellkiteUtvara Hellkite on a big board. Each of those Dragon tokens coming in will trigger either of these, dealing lots of damage. Now, put multiple into play, and we'll seen be dealing a brain-melting amount of damage that can make us steal the game from our opponents.

There are some notable lands and mana rocks (artifacts that help us ramp) that this precon has to offer.

• Carnelian Orb of DragonkindCarnelian Orb of Dragonkind: This may seem like a simple mana rock at first, but if we spent the mana produced by it to cast a Dragon, it gains haste for the turn, so it can attack right away. Neat!
• Cursed MirrorCursed Mirror: A mana rock that can turn itself into any creature we want for that turn (and it'll have haste, too!). One extra combat step? What about second extra combat step? Two Scourge of ValkasScourge of Valkases for more mind-numbing antics. Or copy an Atsushi, the Blazing SkyAtsushi, the Blazing Sky, sacrificing the original to the legend rule (only one legendary creature of a given name can be out on our side of the board at a time), and reaping some value. The world's our oyster here in what we can do.
• Haven of the Spirit DragonHaven of the Spirit Dragon: This is a land we'd typically see if we ran more colors, as this fixes our mana. But still, we can sacrifice this land to bring a fallen sky lizard...I mean Dragon back to our hand.
• Spinerock KnollSpinerock Knoll: This will be easier to trigger than you might think. Seven damage is trivial in a Dragon deck, where it's designed to deal tons of damage. We'll be casting that hideaway card before we know it.

As with every precon, we can make some cuts to improve the deck with some shiny new toys. But what first five cards are we cutting, exactly?

• Commander's SphereCommander's Sphere: If you've been reading the other guides, then I'm beating a dead horse. But the point is we can do much better ramp at three mana, even if temporary.
• Breath WeaponBreath Weapon: We don't want too many wipes, especially if we want quicker games. Besides, two damage is such a rookie number late in the game.
• Goddric, Cloaked RevelerGoddric, Cloaked Reveler: Only conditionally becoming a Dragon is not the way. Besides, there are much better real Dragons we can run.
• Taurean MaulerTaurean Mauler: Including this one. This is not a Dragon (technically it is, but not in spirit). Back on the pastures you go.
• AngerAnger: We have too few ways to discard this card. Thus, I'd rather something that either has haste, or can give it more easily.

For $5 or under, here's what can add instead.

• Ganax, Astral HunterGanax, Astral Hunter: Each Dragon we cast (including itself) makes us a Treasure token. If we end up making a lot of tokens or casting a lot of Dragons, the more spending reach we have. It does cost five mana, but it is five mana well spent.
• Dragon's FireDragon's Fire: We reveal a Dragon, and we're more likely to remove a bigger threat from the board. Great spot removal here.
• Sarkhan, FirebloodSarkhan, Fireblood: A plus ability that ramps us by two (but only for Dragons), or we can discard one to draw one. Ignore the final ability, unless we can pull it off, but the focus should be on the first two abilities.
• Big ScoreBig Score: A second Unexpected WindfallUnexpected Windfall is always nice to have.
• Bolt BendBolt Bend: A neat protection piece, should one of our key Dragons get targeted. We're more than likely to get that discount, too.

On the other hand, if we're in a treasure vault, swimming in gold, here's five more expensive cards to add instead.

• Goldspan DragonGoldspan Dragon: This has haste, and is more than likely to make us some Treasures, which can now make two mana. A great deal for five mana.
• Wrathful Red DragonWrathful Red Dragon: A great way to deter creatures from blocking our Dragons. We can remove other creatures, or forget blocking and hit players instead.
• Ancient Copper DragonAncient Copper Dragon: Hitting someone, and making north of 10 Treasures will send us into Cloud Nine for sure. That's a lot of mana there, and rolling the dice is always fun for sure. In the words of (the late) Sheldon Menery, "embrace the chaos."
• Balefire DragonBalefire Dragon: Our opponents will be scrambling to stop this from hitting them. If they don't, we get to deal at least six damage to all of their creatures, effectively wiping their board.
• Terror of the PeaksTerror of the Peaks: With each other creature coming in, we get to fling a ton of damage around, removing pesky blockers to help clear the way for our Dragons to get through.

If you intend on going on to Bracket 3, here's my advice.

I would begin by adding more protection spells. Deflecting SwatDeflecting Swat is a must here. Then, obviously, faster mana. We can look to both Seething SongSeething Song and Ruby MedallionRuby Medallion for some ideas.

As for Game Changers, it's hard to say no to the value Jeska's WillJeska's Will provides. Meanwhile, Ancient TombAncient Tomb will damage us, but it can ramp us far ahead of the competition.

Those are the main ones to add, but you can add GambleGamble for a spot of tutoring if you wish (watch you don't end up discarding the card you tutored for!)

For both newer and experienced players, this precon's a great pick up. A very simple strategy that helps ease people into the game on one end. And on the other, a template for a mono-red deck, instead of the countless multicolor Dragon options competing for attention all the time. The selection of reprints here are great as well.

For both of these players, this deck gets a solid A, maybe an A- for the experienced players who choose to pursue this deck to add an additional color, since the deck does come with a lot of the needed tools for a Dragon deck.
