Gigantamax Blastoise

The current apex of the Water Dynamax meta, and a great counter to Gigantamax Charizard as of right now, Gigantamax Blastoise is currently sitting in the roughest position among the three Kanto starters. This is due to the fact that Dynamax Inteleon has a a whopping 53% Attack lead over Blastoise, while G-Max Cannonade is only about 28% stronger than Max Geyser when both are at max level. Access to Hydro Cannon helps Gigantamax Blastoise close the gap a bit, but the numbers just don't add up. Add to this the fact that Gigantamax Inteleon is on the horizon, and it becomes clear that Gigantamax Blastoise is good, but sadly outclassed.

Best PvE Offensive Movesets

• Gigantamax Blastoise is locked into a Water Type moveset, even more so than its basic, Shadow, and Mega Formes due to the way that Max Moves work. For this reason, pairing Water Gun with Hydro Cannon* is what currently allows Gigantamax Blastoise to remain competitive.
• Hydro Pump is a good backup if you don't want to utilize an Elite TM.

In PvP, Gigantamax Blastoise is effectively no different from a normal Blastoise, except without access to Return as a move option.
