Reveillark is a deck that's faded out a bit, and is no longer really a Tier 1 deck. A lot of that has to do with some of the really good Time Spiral block cards it lost - such as Venser.
Still, it's a tourney powerhouse, and unfortunately includes several expensive rares. Aside from Lark itself, it packs Wrath of God, Sower of Temptation, Fulminator Mage, Doran, a number of Shadowmoor/Eventide filterlands, and of course, Cryptic Command + Reflecting Pool. So it's not exactly budget friendly; building a straight tourney list will probably run you about $500.
Now, the basis for most Reveillark decks start out with "What are some good CIP-effect creatures?" I don't want to start there; I want to go back and begin from scratch. What are some good 2/X creatures that are good with Lark (whether or not they have CIP effects) - especially ones that are powerful but don't have tourney-deck homes? Or for that matter, what are some off-the-wall ones?Gaddock Teeg
. Gaddock is an amazing card, but the Green + White cost really messes him over. There are better colors for white to splash, and there are better cards for green to splash. And if you're a 5-color deck, you typically don't *want* him on the table. He's a card that basically gets fitted in every so often, but doesn't have a solid home.Heartmender
. Personally, I think this guy is underrated. Put it this way: how do the current Tier 1 decks answer him? Most can't very easily and are basically forced to ignore him. Against control, he's a threat that almost always requires two removal spells to handle; against aggro, it's an indestructable 2/2 blocker.Murderous Redcap
. Redcaps are great as it is, and the ability to recur them for another pair of go-arounds is excellent. I'm surprised he's not in more Lark builds, especially since he's a good weapon to deal with the Planeswalkers floating around.Glen Elendra Archmage
. This critter is amazing against control decks. It effectively forces a 2-for-1, and when recursion is thrown in, it can get absurd.Mulldrifter
. The classic Lark card. It'd be a shame not to mention it.Sapling of Colfenor
. Not exactly what people think of when they think of 2/X critters, but this guy is retrievable by Lark, is a Card Advantage engine on his own, and is another hard to deal with creature.Siege-Gang Commander
. 5 power for 5 mana, but more importantly, a large dallop of board control or burn in a single card.
