vs
Blue-Eyes Spirit Dragon
Card Text: 1 Tuner + 1 or more non-Tuner “Blue-Eyes” monsters
Neither player can Special Summon 2 or more monsters at the same time. Once per turn, during either player’s turn, when an effect of a card in the Graveyard is activated: You can negate the activation. During either player’s turn: You can Tribute this Synchro Summoned card; Special Summon 1 LIGHT Dragon-Type Synchro Monster from your Extra Deck in Defense Position, except “Blue-Eyes Spirit Dragon”, but destroy it during the End Phase of this turn.
Toon Bookmark
Card Text: Add 1 “Toon World”, or 1 card that specifically lists the card “Toon World” in its text, from your Deck to your hand, except “Toon Bookmark”. If a “Toon World(s)” you control would be destroyed by card effect, you can banish this card from your GY instead. You can only activate 1 “Toon Bookmark” per turn.
The Verdict
Case 1: Player-A activates a card effect (MST, etc) that would destroy Toon World on the field, Player-B responds by activating Toon Bookmark from their graveyard, Player-A responds by activating Blue-Eyes Spirit Dragon‘s “once per turn” effect: Toon Bookmark‘s activation from the graveyard is negated and Toon World gets destroyed.
WINNER = Blue-Eyes Spirit Dragon
