Kicker
<i>(You may pay an additional
as you cast this spell.)</i>
As Monstrous War-Leech enters the battlefield, if it was kicked, mill four cards. <i>(To mill a card, put the top card of your library into your graveyard.)</i>
Monstrous War-Leech's power and toughness are each equal to the highest mana value among cards in your graveyard.
