When I first saw this, I thought to myself "What? How is that worth the $40?"... Then I searched around and found out. His +2 ability can be used in conjunction with many, many creatures and artifacts, possibly land and enchantments. Scars of Mirrodin is full enough of possible combos.
Below are a bunch of possible breaks. Plenty of them are pieces of what could be great 3 card combos (Oh god the possibilities...), while some already hold off on there own. I'll leave the third card to you guys.
Also, I'm including the absolute "worthless" combos down here in case it may spark some creativity for you guys.
Acid Web Spider: Destroy a piece of Equipment every turn. I'd rate that a 6/10, as not much people heavily rely on Equipment.
Bleak Coven Vampires: Hot damn, gain 4 life, deal 4 damage every turn? Pretty sweet. 8/10
Contagion Engine: Now THIS is where shit can shine. It's like an ongoing and worsening plague. Every turn, each creature of your targeted player get's -1/-1, or a great -3/-3 if you use Contagian Engine's ability every time. Opponents will have the jolliest of times playing with there NO CREATURES. EVER.10/10
Corpse Cur: Ehh... Might be useful if you're really being destroyed... Bring a creature with infect from the grave to your hand. 6/10
Ichor Rats: Poison counters for everyone! This is pretty much crap in 1 on 1, but could provide some stress and hilarity in a multiway, slowly eating away at everyone, including yourself. Can be good if you are the only one rolling Infect, as long as you can get in an extra poison counter on your enemies before hitting yourself 10 times. Gonna have to give this a 4/10, however, as if you ARE rolling Infect, you could likely wipe out your enemies before you actually get to do this.
Myr Battlesphere: 4 Free 1/1 Myr tokens every turn. 10/10
Oxidda Scrapmelter: Destroy an artifact every turn. Recent sets have been artifact-heavy and just begging for a slap. 7/10
Razor Hippogriff: Return an artifact to your hand from the grave every turn, and gain the artifact's converted mana cost in life. This is damn great if you roll an artifact deck. 10/10
Skinrender: Three -1/-1's on target creature every turn. Can hurt pretty bad. 8/10
Volition Reins: Instead of having it a One Time Use, you can now re-use it so long as you can exile it on time before a creature is destroyed. 7/10
Oh, gonna throw in some extra cards from other sets that may benefit greatly in some way or another.
Bogardan Hellkite: 5 Damage divided any way you want between creatures and/or players every turn. 10/10
Aether Charge: Have this out when you're replaying a beast for 4 damage each turn. 9.5/10
Where Ancients Tread: This is pretty much Aether charge, but for 5+ power creatures and for 5 damage each turn. 10/10
Additionally, once a permanent that uses Charge (or similar) counters is out of counters, simply exile and replay it for a recharge.
Yeah, all of this is pretty basic, but hey, I had an idea and decided I would write this.
Know a great possibility? Comment that shit, I'd love to see it.
