In Magic: The Gathering , the most powerful element isn't fire, air, or water, but the element of surprise
MR: The Marvel expansions are based on the comics, but were always aware of the movies impact, so we find overlap when we can
The problem is that an Animar deck can just explode its hand of dorks on the table by carefully stacking them, and then you have a 6/6 Animar and four or five creatures out there
My first deck had a single Island and Mountain to support two Faerie Machinists and a Shrapnel Blast while being base B/W, and while I felt a bit mana heavy with my land cyclers, it certainly worked out in the end
I understand other people wanted to call it Batman
Items either give a passive bonus or can be activated during a turn to trigger powerful abilities
