Erasure Head

Flash
You may have Erasure Head enter the battlefield tapped. Whenever He becomes tapped, target creature or planeswalker an opponent controls
loses all abilities until He becomes untaped.
{w}: Target creature cannot attack or block until
end of turn. You may activate this ability once
each turn.
The country's still trying to pretend we're all created
equal by not letting those with the most power
excel. It's not rational. -Shota Aizawa
