no
Actually yes. There are some Pokemon (dewgong for example) that are water and ice and ice beats water.
Electric and Grass types. There is a three Pokémon pinnacle composed of Fire, Water and Grass types. It's like paper, scissors rock. Fire beats grass, grass beats water and water beats fire. The electric type is sometimes considered to wriggle its way into the pyramid. Other three-Pokémon pinnacles also exist in the games, (example Psychic, Fighting and Dark types)
Electric
water or ground is your best bet.
You just need to get a good ring on all of them, which will require a good amount of Pokemon purified. For example, Water Type -> Fire Type -> Ice Type -> Grass Type would work since: Water beats Fire, which beats Ice, which beats Grass, which beats Water, and keep going in the cycle. Also, for some reason, you can use Normal Type -> Normal Type -> Normal Type -> Normal Type.

for a full tempo you need to arrange Pokemon so they have an atvantage over the next. (example: fire, grass, water) <------ that's the kind of order they have to be in, but remember that to get full tempo, you need to fill all the poen slots in that particular set(while making sure that each has an atvantage over the next)
