Legendary Creature â Ape Warrior
Kicker (You may pay an additional as you cast this spell.)
If Grunn, the Lonely King was kicked, it enters the battlefield with five +1/+1 counters on it.
Whenever Grunn attacks alone, double its power and toughness until end of turn.
If an effect instructs you to â€œdoubleâ€ a creatureâ€™s power, that creature gets +X/+0, where X is its power as that effect begins to apply. The same is true for its toughness.
If a creatureâ€™s power is less than 0 when itâ€™s doubled, instead that creature gets -X/-0, where X is how much less than 0 its power is. For example, if an effect has given Grunn -7/-0 so that itâ€™s a -2/5 creature, doubling its power and toughness gives it -2/+5, and itâ€™s a -4/10 until end of turn.
A creature attacks alone if itâ€™s the only creature declared as an attacker during the declare attackers step (including creatures controlled by your teammates, if applicable). For example, Grunnâ€™s last ability wonâ€™t trigger if you attack with multiple creatures and all but one of them are removed from combat.
