Creature — Jellyfish Rogue
Whenever you cast your second spell each turn, put a +1/+1 counter on this creature.
The Uthros Combine's first question for any scientific breakthrough is always: "How can this be used to keep our next breakthrough secret?"

- Illvoi Operative’s ability will count any spells you’ve cast this turn, which may include Illvoi Operative itself. It doesn’t matter if the other spells resolved, didn’t resolve, were countered, or are still on the stack. If Illvoi Operative was the first spell you cast this turn, the next spell you cast this turn is your second spell. Similarly, if Illvoi Operative was the second spell you cast this turn, its ability won’t trigger and it won’t get a +1/+1 counter.
- Illvoi Operative’s ability resolves before the spell that caused it to trigger. It resolves even if that spell is countered or otherwise leaves the stack without resolving.
