[Pendulum Effect]

Once, while this card is in your Pendulum Zone, you can negate an activated card effect that targets another "Dinomist" card(s) you control, then destroy this card.

[Card Text]

If you do not control "Dinomist Brachion" in your Monster Zone and your opponent controls a monster that has the highest ATK on the field (even if it's tied), you can Special Summon this card (from your hand).
