Wrath of the Shattered God

(You may cast a legendary instant only if you control
a legendary creature or planeswalker.)
As an additional cost to cast Wrath of the
Shattered God, reveal all God cards in your hand.
Each player loses 2 life, discards a card, then
sacrifices a permanent. Repeat this process for
each God permanent you control and each God
card you own in your hand.
