What kind of magic do you like?

Any summoned creature starts moving immediately after being summoned. On the first turn, the Druid casts Anti-Magic on himself. It doesn't matter what the Mage does. The Druid's turn – summon a Mantis. The Mantis's turn – it flies towards the Mage (even if it doesn't deal damage). The Mage casts Hypnosis on the Mantis. The Druid casts Anti-Magic on the Mantis, and the Hypnosis effect wears off. Now it doesn't matter what the Mage does. With his turns, the Druid will summon Mantises. The Mage becomes useless on the battlefield.
