Llinos Evans 1f0cc46814 Anims for Uppercut, Coin Hurl, and Strong Arm 
Uppercut reimagines KEP's clusterfuck of an animation, reversing Karate Chop and then reworking the sounds

Coin Hurl works like the Poke Ball toss, and then spits out coins on-hit. Looks sort of like Acid in practice. This was weirdly complicated to implement as I had to disentangle the throw animation from the Poke Ball toss in Game Freak fashion.

Strong Arm does the "metal" starting animation, then does its best Rollout into DynamicPunch impression.
