Pendulum Effect
Before resolving a card effect that targets another 'Dinomist' card(s) you control, you can negate the effect, then destroy this card. This effect can only be used once while this card is in the Pendulum Zone.
Monster Effect
If you do not control a 'Dinomist Brachion' in your Monster Zone and your opponent controls the monster on the field that has the highest ATK, you can Special Summon this card (from your hand).
