Combat Trick

Instants that temporarily boost a creature's power and toughness to win a combat exchange or push lethal damage, including Giant Growth, Berserk, Become Immense, and Infuriate. The effect lasts until end of turn and is cast at instant speed so it can ambush blockers or save an attacker from a trade. Distinct from combat.attack_trigger, which rewards the act of declaring an attacker rather than buffing one mid-combat, and from auras or equipment whose pumps are persistent rather than one-shot. Anthem-style static buffs and permanent buff Auras live outside this set since they are not instant-speed tricks.
