Draw a card. Until end of turn, target creature gains trample and gets +1/+0 for each card you've drawn this turn. (A creature with trample can deal excess combat damage to the player or planeswalker it's attacking.)
原文The bonus that the target creature receives is locked in as Fists of Flame resolves, counting the card drawn during its first effect. The creature won't get an additional +1/+0 if you draw another card later in the turn.
