So I'm thinking of buying affinity to get me into the eternal formats Legacy and Modern.

This is just an idea I put together abusing the metalcraft abilities and thoughtcast for card draw.

Spell Pierce is mainboard for facing combo/storm

Arcbound Ravager is $30 a pop I'll buy him later.

Modern build replaces all the artifact lands except Darksteel Citadel with basic lands + Blinkmoth Nexus, Inkmoth Nexus, Glimmervoid and Master of Etherium is swapped out for 2 Steel Overseer and 2 Spellskite
