Keep these in between Max Phases. The rating is how close it comes, on average, to the most Max Phases one trainer reaches against each boss with three of the Pokémon at level 40, out of 100 for the top tank. Some of how Max Battles work hasn't been measured, so parts of the simulation are educated guesses.

Which Pokémon are worth powering up for Dynamax and Gigantamax battles, ranked against every 5★ and 6★ boss.
