Breaker the Magical Warrior reads:
If this card is Normal Summoned: Place 1 Spell Counter on it (max. 1). [...] You can remove 1 Spell Counter from this card, then target 1 Spell/Trap on the field; destroy that target.
I attacked my friend's Breaker with my Blue-Eyes White Dragon, destroying it. My friend said: "Well, before it dies, I remove the spell counter to destroy your trap."
Can she do that?
