I get what the concept is: just abuse the ability to put counters on things to win. But whoa, what a bunch of nonsense. So many 'well it'll be neat if it works!' ideas without dedicating to an idea that would work.

It'll be good to dismantle this one: it is just so clunky. The manabase is all over, the consistency just isn't there and at no point is this deck truly doing something powerful.
