Well, you chose very well.

Also in the information I found, I discovered one of the best Pokémon to use if weaknesses and resistances are reversed: Mega Abomasnow.

7 weaknesses and 4 resistances becomes 7 resistances and 4 weaknesses
Grass type moves go from being super effective against 3 types to being super effective against 7.
Ice type doesn’t change number of types that are weak to it, just which ones.

Just thought it was kinda interesting.
