Round Details + Uses
|Round Move Details|
Round is a Special Normal-type move that damages its target at 60 base Power.
When used by two Pokémon during the same turn, the move’s strength doubles to 120 Power on second use. This effect can only be achieved in Doubles and Triples battles.
Because Round is such a situational move, it really isn’t worth the BP to get it during a normal playthrough.
At most, you’re looking at 180 total base Power spread across two moves, which can be achieved in much more effective ways.
It is further held back by its typing, since Normal-type moves aren’t super-effective against any Pokémon.
One benefit that Round does have is that it can be learned by nearly every Pokémon, so it isn’t too difficult to find a Pokémon with high Special Attack to teach it to.
