You can only activate 1 card with this card’s name per turn.
(1) When your opponent activates a Spell/Trap Card while you control a “Dragunity” Synchro Monster: Negate that activation, and if you do, banish that card, then, if you control a Level 10 “Dragunity” monster, 1 “Dragunity” monster you control gains 100 ATK for each card currently banished face-up.
