>>43886849How to fix:
1. Let it learn Recover and Refresh.
2. Make "RKS system" into a key item. Use it on Silvally to set its type. Now Silvally can hold an item.
3. Change Multi Attack so it matches the user's typing. If Silvally acquires new typings, such as if it is a Fire Type and Trevenant uses Forest's Curse on it, it is now a dual Fire/Grass move. If Silvally gets soak used on it, Multi Attack is a Water type move now. That sort of thing.
4. Now that RKS System is an item instead of an ability, we are free to give Silvally an actual real ability. I would suggest Super Luck, Pressure, or if you want to go with the theme of screwing over ultra Beasts, Unaware (so that it can ignore Beast Boosts, although with all that bulk and recovery Unaware Silvally would be a god tier stall pokemon). Adaptability would be fine too, and also fit with Silvally's themes.
Optional: This might be a bit crazy but, what if Silvally could learn Topsy Turvy so that it could REALLY fuck over Ultra Beasts and their Beast boosts?
