How about I play Chandra (following the third idea), but instead of Liliana or Nissa, you would play your fanwalker? And for the Magic spells, that sure could work.

Also, I was thinking that maybe we could play Magic in the rp, like our characters have cards that allow them to cast or summon actual spells.

I'd prefer it if we were our own Planeswalker characters, if you don't mind. I kinda like the third idea though.

Maybe something involving Liliana and Chandra? I have a few ideas.

1. After Bolas wins on the Gatewatch, Lili and Chandra go live together on Innistrad. One day, Chandra surprises her girlfriend in a messy diaper, and becomes Lili's diaper changer/dom. It could be nice if Chandra tried diapers later in the story.
2. Many years after the Gatewatch's defeat, Chandra, who took a break from planeswalker duties, decides to go sse Nissa on Zendikar. As with the idea number 1, Chandra surprises Nissa (instead of Liliana) in a full diaper. Again, Chandra could wear diapers later on the story.
3. For this one, Chandra is the one who's diapered. She enjoys wearing (and using) diapers when she's alone at home. Nissa (or Liliana), who's unaware of that, goes at Chandra's house at the same moment where Chandra's in just a diaper.

The things I can do include: wetting, messing, hypnosis, spanking, mental regression (not physical regression, though), pacifiers, and enemas/laxatives.

I is. What did you have in mind?

I saw that you were interested in a Magic: the Gathering RP last year. Are you still willing to do one? Message me back if interested.

She messed even more, also soaking her diaper.

I giggle as e're lifted off the ground by our monstrous diapers.

She messed more and wet herself quite a lot.

I laugh and mess with you, our diapers quickly touching the ground and continue swelling.
