Yorion Sky Nomad and Ugin's Conjurant

Asked by 9-lives 1 year ago

If I have Yorion, Sky Nomad's ability trigger and choose Ugin's Conjurant with it, what will happen to the paid mana cost of X before being exiled, and then brought to the battlefield on the beginning of the next end step? Would X change? Or would it be 0 or infinite?

The only time the X in the cost of Ugin's Conjurant 'matters' is when its on the stack. As it enters the battlefield, it refers back to the value of X on the stack to see how many counters it enters with. Once it's on the battlefield, it has no memory of how much X was, and is just a base 0/0 creature with however many +1/+1 counters it has on it.

If it enters the battlefield any other way, like if it's exiled and then returned to the battlefield with Yorion, Sky Nomad, it'll fail to find a positive value for X and will just enter the battlefield as a 0/0 and immediately die due to State-Based Actions (unless you have something else which causes it to not have 0 toughness when it enters, like Always Watching or... Rules Lawyer).
