>>44212532Not really, Porygon-Z doesn't even have a GMAX form but with the right build his Dynamax is insane, also you are not considering lots of factors like team build and composition, in some battles a mon that usually wouldn't be your carry might be the best to Dynamax, or if you lose a pokemon early and feel pressure you can respond with a Dynamax to regain tempo.
Theres inumerous ways to be creative with Dynamax, saying something like "Just use GMAX in your best mon and win" is pure ignorance, its like people who don't play PvP and think all you need to do is stack a couple of good pokes, when in reality Doubles requires lots of synergy and good reads.
