Unfortunately, there was no type advantage, and he did not even know whether it had landed a critical hit. Gems could also increase a move's power, but gems were single-use items; using one consumed a gem.
This all-out combined attack reminded him of Z-Moves. Both were high-burst moves. Being able to inflict such damage on an Elite Four Trainer while below Elite Four level meant it was comparable to a Z-Move with around two hundred power!
