Unleash the Dominator

This spell can't be countered.
As an additional cost to Unleash the Dominator,
you lose 8 life and must sacrifice 2 lands
Target player sacrifices all permanents they
control, exiles the top 30 cards of their library,
and discards their hand: You get 6 tyranny
counters.
(Tyranny counters cannot be proliferated, if a player
has 8 or more tyranny counters, they lose the game.)
