[Modern] Mirrodin Block: Affinity and Modular

As money permits I have been trying out specific abilities from each block in Modern. Mirrodin is the first block of this format, and Affinity its most famous and infamous ability. It is still a dominant deck in Modern even after getting most of its cards banned. This build is casual and good just to earn how this ability works. There is also a modular card in this deck (Arcbound Worker).
