Jovani's Contract

Shroud
Enchant Player
Play this spell only if you control at least one
creature. Jovani's Contract can only enchant a
player who controls at least one creature. You
and enchanted player combine life totals and now
share a life total for as long as you control
Jovani's Contract. If you or enchanted player
control no creatures, sacrifice Jovani's Contract.
The remaining life total is divided in half between
you two, rounding down.
