Agreed. I've moved away from U/B a while ago. It is relevant in a heavy green meta, but there are just SO FEW decks that pack green that it could be relevant against. In saying that I know that perish does very little against VV. They are too resilient and recover too well from one. I for one have not played too many zoo decks in recent days and the ones I do play side out their green creatures game 2. Usually bringing in more removal and REBs.
