Attention duelists! This is Crystal Keeper (FLOD-EN093), a Common rarity card from the Flames of Destruction Unlimited Edition set. If you run a Crystal Beast or Ultimate Crystal deck, this card offers some handy protection and a power boost.\n\nHere's what it does: As a Pendulum Effect, once per turn, it prevents the first Crystal Beast card or Ultimate Crystal monster you control from being destroyed by a card effect. As a Monster Effect (Quick Effect), during damage calculation, if your Crystal Beast monster battles an opponent's monster, you can Tribute Crystal Keeper from your hand or field to double your monster's original ATK/DEF for that battle – but your monster is destroyed at the end of the Damage Step. It's a strategic card that can save your key monsters or help you win a crucial battle.\n\nThis is a single card, not a full deck or pack. Condition is typical for a Common unlimited edition – great for play. Whether you're collecting, trading, or building a competitive deck, Crystal Keeper is a useful addition for Crystal Beast fans. Duel on!
