Ill look at all gender and all stats, this might go on for a while so please don't be offended if I didn't pick your design.

For Heir/Lions:
I'm not a big fan for golden base but I'll probably base change him/her to ice or cherry blossom, so if they look good in that base I might buy it! If you even give me a design that'll persuade me that works too xD!
Here's some of my lions to give you some ideas^^!
Wine
Night and Sunset
Altair
Marga
Like
- blue / red / maroon base
- margay / cel / ice / maroon / ginger / white lace markings
- rosette
- colorbomb / pastel / purple(?)
- auburn panther!!
-onyx(or dark base) with white markings
Not a fan of
- golden base/ markings
- saffron
- lilac lace (I do like other lilac markings though!)

For Leopon
I need a Leopon to freeze, the only requirement is he/she needs to have molted rosette or onyx Rosetta ^^
I'm planning to take out other markings for customize and change base so they don't matter ^^
