A "Special" Transforming character

I'm trying to create a character who transforms automatically in battle every few turns.
The current way I have this set up is in a Troop, it checks to see if this character is currently in the transformed state. If not, then it calls upon a common event which forces the character to use the transforming skill, which activates a state, which calls upon ANOTHER common event that changes the characters graphics, class, abilities, etc.
However, attempting to have the character then automatically un-transform after another few turns is proving difficult. He's getting caught in a loop.
I also don't like the fact this causes the character to waste a turn.
I'd like it if after every 3 turns or so the character either transforms or un-transforms, without wasting a turn.
I feel like this can be done without scripting, but trying to figure out how to accomplish it myself is giving me a headache.
I COULD just make this ability in control of the player, but I'd rather it be an automatic part of the character that the player has to strategize around.

Since you have a common event that activates a skill which activates another common event, why not skip the skill activation? You can play animations and add states in events too in case thats why you use a skill

That way you will probably not waste a turn too

So I was basically overthinking it WAY too much. Thanks for the tip.
