Mariah

Bastet’s Outlet — Whenever an opponent activates an ability of a nonland permanent, put a Magnet counter on that permanent. Increased Magnetism — At the beginning of each opponent’s combat phase, Mariah deals damage to that player equal to the number of Magnet counters on permanents they control. Crushed by Metal — {2}{R}: Target creature an opponent controls with a Magnet counter on it can’t attack or block this turn. If that creature has three or more Magnet counters on it, destroy it. {/color#ffffff}
