2 rulings from Wizards of the Coast
- 22 January 2016Jori En’s ability can trigger only once each turn. The ability will resolve before the second spell resolves. It doesn’t matter if the first spell you cast that turn has resolved, was countered, or is still on the stack.
- 22 January 2016Jori En must be on the battlefield in order for the ability to function. Notably, the ability won’t trigger if Jori En is the second spell you cast in a turn.
