if you used that livewire lash/distortion strike combo, wouldn't that give you an automatic 3 poison or -1/-1 counter on top of what ever the creatures power is? or do buffs not work that way with infect?
Darksteel Colossus, mainly because the art reminds me an evil version of "The Iron Giant". But it's also a pretty sweet card.
