yes ice is super-effective against grass
you have to have an electric dragon/ice and if you want a water
Have a water ice or grass pokemon.
Ground is weak against water, ice, and grass types.
Hope and pray while using a ice/grass pokemon
Grass, Flying and Rock types.
Fire.The fire will burn the grass and also ice,flying,poison,and bug type :D
The following are good against ice type Pokemon... Fire Grass Ice
A Fire-type Pokemon can deal 2x the damage to Grass, Ice, Bug, and Steel-type Pokemon.
mahogany town talk to old man if he doesnt give it beat him up for it
You get ice types on the ice path.
You can use a strong Pokemon to hit all the Elite four's Pokemon and champion Lance's Pokemon (in HeartGold). It depends on your Pokemon level but you can use ice types to beat Lance's Pokemons so it's easy to beat Lance.
maybe water, rock, ghost, pyshic, grass, rock OR... grass water flying fire bug dragon/ice
