Deathclaw Giovani

Exiling the creature card with scavenge is part of the cost of activating the scavenge ability. Once the ability is activated and the cost is paid, it’s too late to stop the ability from being activated by trying to remove the creature card from the graveyard.

If a creature card has multiple instances of scavenge, you can activate either ability (but not both, as the card will be exiled when you activate one of them). Young Deathclaws’s ability doesn’t affect the scavenge cost of a creature’s other scavenge ability.

If the creature card you scavenge has {X} in its mana cost, X is 0.

The number of counters that a card’s scavenge ability puts on a creature is based on the card’s power as it last existed in the graveyard.

While Young Deathclaws is on the battlefield, the scavenge cost of a creature card in your graveyard is equal to its mana cost, including any colored mana requirements.
