Metagame Foresighters

[chartung17]

Few questions
1. How does Wish turns work if Wish is in the first slot? And a matter of that fact, how does Future Sight/Doom Desire work here?
2. How would the Pledge moves work here?
3. How does Fusion Bolt/Flare work here as well (though this would only be possible with Smeargle and Ubers variant of this meta).

Wish heals four turns after it's used.
Future Sight works as it normally does, whether it's in the first slot or another slot.
Pledge moves do not activate their combo effects.
Fusion Bolt/Flare do double each other's power.
