Dual Type Buff

Had some thoughts on what buffs they can implement for dual types. Wondering what your opinions will be on it

Silvally’s Memory disc’s/Arceus Plates:

They can work like tools, so when attached, they can give the user an option to pull energy from the specific type of the memory disc/plate. So if i wanted to run a dragonite deck, i can have one of these plates attached to dragonite if i get unlucky and never pull one of the other energies needed.

Or it can work as a 1 time use item as well

Protean ability:

Something like where Greninja changes his typing to the corresponding type, but instead of changing the pokemon, it changes the energy type. Might be where it’ll still randomize what energy it changes too, so you can still be unlucky and it randomizes to the same energy, but at least there is a chance to get the energy you want.
