High-cost spells can win you the game, but they're likely to sit in your hand if you don't have the resources to cast them
The Fiend's heads effect lets it pop a monster and inflict burn damage to its controller whenever it battles, while its tails effect basically Dark Holes the entire board when it battles
Aside from that, this card requires you to pay 1,000 LP to attack with it, which can be a problem if you play it late in a duel
Cards like Soul Warden , Serra Ascendant , or even incidental lifelink turn this into a snowball thats hard to stop once it starts
