Twilight Decapod

Multikicker {u/b} (You may pay an additional {u/b} any number of times as you cast this spell.)
When Twilight Decapod enters the battlefield,
target opponent mills twice X cards, where X is
the number of times Twilight Decapod was
kicked.
As long as an opponent has ten or more cards in
their graveyard, Abyssal creatures you control
have menace.
