Opponent targeted their 1/1 illuminator virtuoso with a slip out the back, I cast caboreti charm on the first mode in response to the connive trigger. In response to that, they cast another slip out the back and triggers another connive. The first connive triggers, it becomes a 2/2. The Slip out the back resolves and the creature is phased out and should come back as a 3/3 at the end of turn. At the end of the turn it returns as a 4/4.
