Pineapple Blast
Card effect (current official text)When you Normal Summon a monster, if your opponent controls more monsters than you do: Destroy your opponent's monsters so that your opponent controls the same number of monsters as you (your opponent chooses which of their monsters are destroyed).
Rulings
- When Ring of Destruction or Call of the Haunted is chained to Pineapple Blast, and the number of monsters on the field is changed, count the number of monsters at resolution of Pineapple Blast's effect, not at activation.
- If, when Pineapple Blast resolves, you have no monsters, all of your opponent's monsters are destroyed too.
- If you Summon a monster and want to activate Pineapple Blast, and your opponent wants to use Trap Hole, Pineapple Blast is Step 1 of the chain and Trap Hole is Step 2.
