Go Zanz! 8)
IMO, super slow way to trigger death effects as you need lots of entropy quanta to trigger effects turn after turn, and in all honesty, those effects are not so epic. +1|+1 on condors, boneyards generating skeletons, and +2 counters on bonewall, and of course, your deck will usually have just 1-2 cards that benefit from death effects anyway.
Fractal Balls of Lightning works much faster, and its still not a good competitive deck.
On the side note, if the Cat keeps buffs, it may be immune to Antimatter? Something to test in trainer.
