How to get past the final masters of poison battle

So Iv only recently started playing, and passed the first 3 battles easily, but no matter how many times I try and whatever selection of moves I use I can’t seem to win. Is there any specific way people mange to get by it?

Skip with the water monster all the time, and just poison touch the 4 starters one at the time. To deal with the Voltigers use poison touch to poison eater, but make sure when you use poison eater the first time not to leave a monster that takes a turn early, otherwise he’ll use timestrike.
