Metyr, Mother of Fingers

Menace

When Metyr enters the battlefield, create X 1/1
colorless Hand creature tokens with Menace and
Haste. At the beginning of your upkeep, you may
have Metyr deal X damage to target creature or
planeswalker. When Metyr attacks, it gets +1/+0
for each Hand you control. When Metyr dies, you
may deal 1 damage to any target for each Hand you
control. When Metyr attacks, it gains flying until
end of turn.
