hasn't anyone realized Tentacool's PP Cowardice is not that bad?

if you use it in a damage swap deck with alakazam you can swap 20 damage on to 'Cool and use cowardice then put it back on the bench and swap 20 more damage on to it and use cowardice keep doing this and you will be unbeatable unless your opponent hits you for a 1 hit KO.
