Calyrex As one ability

[Saltypineapples]

I was wondering if I could somehow cahnge the ability of a Calyrex rider (As one).

What I mean by that is that for exaple I could have a Calyrex with instead of Grim neigh and unnerve it would have like Skill link and Serene grace.

Is that possible or not?

Thanks in advance

With ROM hacking, probably.

If I recall correctly, the effects of the 2 "As one"s are hard written; they're not based on variable abilities. They're just made to look like it's combining 2 existing abilities together.

If you're good enough at coding, you can make them appear as anything.
