Veil of Equilibrium

When Veil of Equilibrium enters the battlefield
create a 1/1 Soldier creature token with "When
this creature dies, you gain 1 life" and a 1/1 Ooze
creature token with "When this creature dies,
you lose 1 life."
Non-token creatures you control get hexproof
from converted mana cost X, where X is the
amount of life you gained this turn minus the
amount of life you lost this turn.
