>>51003440no.
not the same logic.
Rock is pretty much just a worse Ground at everything except hitting Flying types.
Just make all Rock-type Pokemon Ground type, all Rock-type moves Thousand Arrow-like and you're good to go, you successfully removed a type and nothing has really changed (except for Grass/Rock types unfortunately)
You absolutely cannot change all Ice types to Water types. How the fuck is Mamoswine a Water type? How the fuck is Weavile a Water type? How the fuck is Garm a Water type?
What do you even do for type effectiveness? Did you just fucking buff Water??
What do you even do for the moves?
