Ragefire Hellkite (V.1) - Dominaria United: Extras (Rare) [XDMU-285]

Ragefire Hellkite is a five-mana Dragon from Dominaria United with flying and a powerful ability. Whenever it attacks, you can sacrifice another creature to give it double strike for the turn, allowing you to deal significant damage and potentially finish off opponents quickly. It fits well in aggressive red strategies that can generate and sacrifice creatures efficiently, but be mindful of needing a creature to sacrifice for the double strike effect to activate.
