ALLMO Battlecube

When ALLMO Battlecube enters the
battlefield, create four 1/1 colorless MO
artifact creature tokens.
Whenever ALLMO Battlecube attacks, you
may tap X untapped MO you control. If
you do, ALLMO Battlecube gets +X/+0 until
end of turn and deals X damage to the
player or planeswalker it's attacking.
