Can be used each time your Life Points decrease by 2000. Show 1 monster card in your hand to the opponent and roll the die once. The Level of the monster shown becomes that of the die number until the end of the turn.
...Is there even a card other than Extra Gate that cares about the Level of a Fusion Monster in the Extra Deck? (There certainly isn't one that cares about the Level of one in the hand, for obvious reasons.)
Four in Six chance to summon Level 5 and higher monsters without a sacrifice? Sign me up!
