FOOL! Spell

Troll/Annoying (It's true right XP.)

You can only cast this card if your opponent activates a card effect

Cast Cost: Shout FOOL!

[Counter] Nullify the effect, even if it can't be nullified, then inflict 2 damage. If your opponents facial expression is similiar to this: (ﺧ益ﺨ) you can add this card from the drop zone to your hand. Both effects can't be nullified, even by another FOOL! Unless used by Writer7.
