Yeah, I hear you. In my group, I wasn't the first to pop Exanguinate, but I'm the only one who uses it regularly. I'm just waiting for others to start matching me with the big spells. The arms race has yet to start here, but it's a matter of time. As I consistently wipe out the group with exsanguinate, recurring nightmare, and other sick cards, someone will eventually stand up and stop bleeding to respond in kind. Then things will get really interesting...
Like, I shut three creature decks down in a game the other day where everything I played was an artifact or land (esper, mainly) and strangled them under three Cumber Stone
s, a recurring Scourglass
and two Icy Manipulator
s. No one in the group except me plays artifact and enchantment sweepers. A single sweeper would have wiped me out. I don't even play with Darksteel Forge
So yeah, I hear you.
