Here's a question that's been bothering me for a while.
Let's say I have a Zoroak (with Illusion). It changes into the last pokemon in my party. I've encountered people who say stuff like "sometimes I have Zoroak appear like my Breloom, other times like Keldeo."
If Zoroak changes into the last slot into your party, how do you control what it becomes? Can you change it mid-match? And what if the last pokemon in your party is dead? Does Zoroak become a dead weight?
