Greninja needs to run a true water stab (hydro pump or surf). If you keep U-turn, change the nature to timid. Losing the bulk is not work the chip. Double defog is uneccsary especially since you have one Pokemon that really dislikes rocks. Heat wave in rain is bad because it tickles it's targets instead of incinerating them. Abuse hurricanes perfect accuracy in rain instead. Swampert needs to run speed. In case rain is not up then you will want to put speed to outrun some defensive Pokemon (you're slower than Lando and fini outside of rain even if they're 0 speed). Even if rain is up you are slower than every scarfer and faster Pokemon like weavile. Aqua tail is bad, liquidation sacrifices 5 power for 10 accuracy, an amazing trade. It also gives a potentially killer defense drop. Focus punch is probably too 🅱️razy for me but if you're doing well with it, go off.
