Hows Knock Off Tentacruel working for you? I've had more success with Ice Beam or substitute (when using a rain team) in its place.
Very well, actually. Apparently a hail team that hit #1 on the LBs in B/W had a Knock-off tenta. I didn't know what set to put on it so I used the team builder and saw Knock-off and was like "hey that seems useful for getting rid of leftovers and choice!" and went with it.
I have enough ice and tenta doesn't really abuse sub that well since it isnt offensive so I like knock-off.
