黑山之威血爪

Text:

由你施放且力量等於或大於4的生物咒語減少來施放。
每當黑山之威血爪攻擊時，直到回合結束，每個由你操控且力量等於或大於4的生物各得+1/+1且獲得踐踏異能。

Rulings:

• 7/13/2018 If you cast a creature spell that will enter the battlefield with a number of +1/+1 counters, such as Hungering Hydra, those counters aren’t considered when determining whether Goreclaw reduces that spell’s cost. Similarly, effects that will raise the creature’s power once it has entered the battlefield won’t apply.
• 7/13/2018 If another creature has an ability that changes its power when it attacks, such as Brawl-Bash Ogre, you may have that ability resolve before Goreclaw’s last ability.
• 7/13/2018 Goreclaw’s last ability affects only creatures you control with the appropriate power at the time it resolves. Creatures you begin to control later in the turn won’t get either bonus, and a creature you control whose power decreases later in the turn won’t lose either bonus.
