Useless hero abilities
1) Whirlwind --> bounce a random zombie away. This is probably worst trick in game which has often even negative moment on your game if you want to play it.
2) Bubble Up --> Move a plant. It gets +3 hp. Idk, maybe if it aswell drawed a card? Now it is one of the worst tricks. You already get * by tricks.
3) Root Wall --> A plant gets +2 hp and can't be hurt this turn. Maybe if it made that plant immune to tricks aswell. Now it just sucks most of the times
4) Dolphinado --> bounce a random plant. Same as whirlwind, but sometimes with pet decks it can be ok.
Other good mentions but not as useless as those four
5) Rock wall --> a zombie gets +5 hp. Definetly better than Bubble up since plants don't use trick so easily on you.
6) Posessed --> a zombie gets +2 hp and frenzy. Sometimes usefull, usually bad but not totally worthless thou.
