I'm responding to Demonito's Tentacool article.
No, sorry, but you can't heal all of your pokémon's
damage when tentacool is out. you cannot keep swapping 20 damage on
tentacool, pick it up, put it down and repeat in the same turn, you can only
heal twenty damage once per turn.
Tentacool's Power says:
Any time during your turn(before your attacl) you
may return tentacool to your hand.(discard all other cards on tentacool)
This power can't be used THE TURN TENTACOOL IS PUT INTO PLAY or if tentacool
is asleep, confused or paralized.
So all you can do is swap damage to tentacool,
pick it up and put it down. if you were able to use cowardice as much as
you like, tentacool would be too powerful. tentacool is still good,
though. i remember the time i kept doing twenty damage to an alakazam
and he kept healing it with a tentacool! I was getting no hits off of
him!
