Some people are complaining about Poison Heal since SubHeal Rev would be OP, but I wonder why it would be this more threatening than Gliscor. We discussed about it on PS!, I believe that if SubToxic Gliscor isn't seen anymore (or at least way less often than in BW), it's because he has trouble against the like of Sableye-Mega, Celesteela and Skarmory, and so does SubToxic Revenankh, who has an even worst match-up against Tapu Fini, Toxapex, Mollux and Magearna (unless you have a room for Power Whip or EQ, which doesn't ensure your Victory against these threats either). Furthermore, Rev is slower than Gliscor and thus Taunt is less useful on him, but without this, he becomes a Set Up Bait for some Mons like Scizor-M and Zygarde. I don't think that the typing is a solid argument either and that having a quadruple weakness on Ice and a normal one Water is still better than being weak to Fairy, Psychic and Flying in the current Metagame. Among the threats I mentionned, most of them have way more problem against a SubBU Rev than a SubToxicTaunt one. Therefore I don't think that Poison Heal is a big distract which prevents you to use Bulk Up Rev. I like Triage very much too though.
