Trivia Eternatus Eternamax form is still capable of using Max moves despite it not technically being a Dynamax form
You can go Voltron (and that's likely where most people will go), but you're in colors that support pillow fort, prison/stax, or even just plain stompy
And without the ability to move damage around, spread attacks that wouldnt be game-breaking against regular Pokmon are relegated to unviability
The best advice I would give anyone trying to qualify for Pokmon TCG Worlds would be to give yourself as many chances to obtain CP as possible and to frontload your event schedule
While it could use some protection (enter Temple Altisaur), being able to discover X once per turn based on the toughness of a Dino entering the battlefield is a huge play, and one that can snowball into an easy victory if your deck is stacked the right way
If everyone who trades cards uses TCG median, then whats the point of TCG low and TCG high
