Entering Infinite

Whenever a player casts a spell, that player draws X cards and loses twice X life, where X is the number
of spells they've cast this turn.

{6}{u}{b}{b}, Exile Entering Infinite: Draw X cards, where X is half your library, rounded down. You lose Y life, where Y is half your life total, rounded down.

Knowledge is power... And like power, too much of it will destroy you.
