Total Party Kill

Each opponent exiles all even or odd creatures from
their command zones, hands, libraries, battlefields,
and graveyards. They shuffle their libraries after.

Until the end of the game creatures you control
have Deathtouch and Wither, and whenever an
opponent attacks you, each attacking creature they
control has Decayed.

this one anyways."
