If Keyhole does what it looks like (trashing one of the top 3 cards on R&D) it seems really powerful. Like: zomg powerful. Noise is an unholy trashing terror thanks to recursion and Sahasrara already.
I'm dubious about TGTBT, since we have decent flytrap effects already, and at 3/1 with no ability? Meh.
Counterstrike is nice since it doesn't require a tag, but is weak to existing meat damage defense, which is already prevalent in my meta .
