Could I stop another player from ever creating more than one token for Esix, Fractal Bloom to affect on their turn by giving them the spirit in their upkeep from Forbidden Orchard or does it not count the token given to you?
- your opponent controls Esix, Fractal Bloom
- they have e.g. a sorcery to create a lot of tokens
- they have a good creature to copy
- you want to limit them to only one copy on their turn
then yes, you can activate Forbidden Orchard to do this. Esix does not care about who controlled the trigger, it only cares about who created the token, which in the case of Forbidden Orchard is your opponent.
