Slash Perish Song with HP Fire, U-Turn is too usefull on Celebi as badabing said it above. Thunder Wave isn't really usefull on Celebi.
QC have discussed this at length, both in this thread and on IRC and we all agree that Specially Defensive and "Physically" Defensive stay on as two different sets. Both sets were seperate in the old analysis, and in my mind, nothing has changed significantly to result in the 2 sets being combined. They check very different things, and therefore are different sets. We already have a precedent for this, Specially Defensive and Physically Defensive Skarmory both work in the same way, they have the same moves, and yet both sets check different things and are separate sets. This is no different.I can't say I agree with two defensive sets. Same moves, item, similar spread, but opposite stat... Just doesn't seem like it would be worth a whole other set.
