The World Tree

Each time a face-up Plant-Type monster(s) on the field is destroyed, place 1 Flower Counter on this card. You can remove any number of Flower Counters from this card to activate these effects.
• 1 Counter: Target 1 Plant-Type monster on the field; that target gains 400 ATK and DEF until the end of this turn. (This ATK gain remains even if this card leaves the field.)
• 2 Counters: Target 1 card on the field; destroy that target.
• 3 Counters: Target 1 Plant-Type monster in your Graveyard; Special Summon that target.
