good suggestion.

however, the flying ability of the bird is an evasion by itself. thus, the lens would be most likely ineffective. however, equipping "walking" creatures would optimize the lens' potential.

i prefer green on this one.

equip the lens in a, let say, a putrefax... imagine the dilemma it could create... or a blight mamba perhaps... let me draw or get infected...

i bet you would rather use proliferation to stack up the poison counters than use creatures in getting things done... i understand.
but i prefer slugging it out with creatures rather than spells.

i would use proliferation in other effects... to speed up the "ultimate" effect of a planeswalker perhaps...

just my opinion.

now... semblance anvil! this one, i want to abuse! imprint on it a planeswalker... voila! cast the superfriends 2 at a time! or myr... nice!!!
