(No🗡️) Outrage/(Target) Body Slam Gigantamax Snorlax Duo Battle, Windy weather, T2 helper + Shroom

In a Duo Battle, it would take ~27 seconds to charge up Max Meter considering switching and dodging time costs. With 27 seconds, the Gigantamax Battle Boss can use 3-5 attacks, depends on how fast those attacks are.

With Gigantamax Battle Boss got stronger in 2nd phase, their attacks hits 6x as hard as they were in 1st phase. It is very difficult to survive 6x power moves 3 to 5 times, even if the boss itself has weak attacks.

However, there are always exception, and Gigantamax Snorlax are one of them. It learns Outrage, which is triple resisted by Crowned Sword Zacian, and also Body Slam/Heavy Slam which have low base power and resisted by Crowned Shield Zamazenta. With Gigantamax Snorlax low attack stats, those move would only hit "normally" even at a 6x multiplier.

It is important if the team can survive 2nd phase or not, since 2nd phase last longer than the 1st phase. In this case, since Crowned Shield Zamazenta and Crowned Sword Zacian can work together and keep surviving, there is more time for Gigantamax Machamp to attack. So, even when Gigantamax Snorlax has rather high stats as a boss, the team can still defeat it with only Max Mushroom and minimum damage boosts.

It is not trivial to survive at 2nd phase, though. Since Snorlax hits extremely hard, Crowned Sword Zacian would want to make sure it is near full health every time a Max Phase is end, so it can absorb a lot Outrage attacks without being defeated.
