Machamp SF's "Take Out", that needs to be brought back IMO, I'm not a fan of basics that have 130HP and make a mockery of Stage 2s. "Take Out" should be rebalanced so it's not used to donk poor Weedles and Caterpies, adjusting the energy cost should suffice. I wanted to say it shouldn't KO Legends as well, but it could be of low priority since it's a retired mechanic.
