Evil Eye Mesmerism

When your opponent Special Summons a monster(s): Activate this card by targeting 1 of those Summoned monsters in Attack Position, with less ATK than an "Evil Eye" monster you control; take control of that monster. When that monster leaves the field, destroy this card. While "Evil Eye of Selene" is in your Spell & Trap Zone, that targeted monster is also treated as an "Evil Eye" monster. You can only activate 1 "Evil Eye Mesmerism" per turn.
