Ugin's Sacrifice

Exile up to three target colored nonland permanents with total converted mana cost
6 or less. If you control a Sorin planeswalker, add one loyalty counter to it.
Ugin challenged Bolas to a fight over Bolas's Citadel. Sorin watched in horror as the citadel crumbled to dust at Ugin's command, and Ugin
at Bolas's.
