first time i saw soak i tought that was useless,but later i tought some strategies that can be made with it,some are:
-make pokemon with a lot of weakness have just 2 weakness,and grass is really uncomon(excluding ferrothorn)
-make shedinja almost imortal
-make sure that your eletric moves will be superefective against your oponent and remove their stabs
whats your opinion?it has future to at least double battles or will be forgoten?
