There’s so many mounts at this point but sadly there are just specific mounts that’ll let you go faster or provide stats and the mount might not be your favorite, maybe you think it looks ugly but you gotta be apart of the meta. So why not KI add a stables to wizard city where you go to and you can upgrade any of your mounts speed, maybe add stats on it like jewels and maybe even add the option to stitch your mount at this stables idea especially since the Dino bonus set still exists and not everyone is a big fan of the dinos, at least being stuck with them forever because there’s no set bonus better than that since then.

topaz bone
green steppe
I think another suggestion to this was similar in result, which was mount and pet stitching so you could have the look of one but the speed (or cards for a pet) of the other
raven quarry
They can supersede the mounts too, make mount jewels with stats, for crowns. To include better and more types of stats, including resist, shadow pip rating , etc.
The current mount stats are:
- Speed
- Damage
- Accuracy
- Pip chance
- Pierce
- Outgoing healing
This way we all get the chance of obtaining the best mount stats on game, with any appearance, and it generates more income for KI.
Or they can make recolours of current mounts with stats.
