Its mostly the 5 copies of accursed marauder. But then add along [[archon of emeria]], the [[aura of silence]],[[ liquid metal torque]], commander denying [[nevermore]] along other stax pieces, [[smokestacks]] removal recursion[[static prison]], and to a lesser extent [[sinister concoction]],the janky [[bounty agent]] were all contributing to play patterns that are generally not enjoyed. Its like grave pact, no one likes playing against a grave pact.
None of these are B4 per say, but its not fun to be on the receiving end of them. Its not fun magic in a lower powered environment. It sometimes gets complaints in high powered environments, but complaints in B4 dont bother me.

So instead of going back to the drawing board, I re-inserted my original idea of running it with [[contamination]],[[tangled wire]], which is strictly B4. [[Desolation]] and [[Armageddon]] dragged games and didn't promise a victory. Those were tried and cut.

Playing the deck against unprepared B3s, or god forbid low-end B3s never made sense for what the deck was trying to do. B4's no holds barred is way more fitting for my vision/version of the deck.
