I feel 70 damage between turns would be more balance but the cost seems about right for such damage. The card seems solid overall. One energy for a possible 120 damage is fun. I think the thing people are missing here is its a Stage 1 Pokemon.
The Issue with that example is you assume the opposing player sets up Toxapex-GX that way, when it can get rather complex real quickly in practice:
-The player can easily just place an alternate attacker like Hoopa or their own Tauros-GX to develop a benched Mareanie, as well as add an Assault Vest for more protection.
-The Player can use Wally to get it up and running turn one.
-The player, if faced against Tauros-GX as the active pokemon, can easily use this card's own Z-Move to prevent damage done to it.
Of course, I wouldn't exactly try a 1-Turn setup just for the Poisoning attack either - I would rather do careful development at the start, and deal some preliminary damage with the first attack. Max Potion and other healing could work well here, while averaging 60 damage each turn with spike cannon.
Either way, I won't count off its viability just yet - It just needs testing first.
And in fact Tauros Gx cannot Sevrive at ALL. he can kill him with the Gx Attack ones, but at least the poison count and is a Trade 2 price from 2 price
I'm not trying to build a damn perfect list I was just informing you people of this cards potential power. I could care less if tauros GX one shots Mareanie and toxapex because it won't be played.
What are you having out as a body to take on your opponents Pokemon, as you set this up?
Don't blindly play the card out in your head, think about what your opponent has to answer it.
The much more viable TaurosGX, solos this card. Easily.
OHKOs Mareanie with a DCE attachment.
OHKOs ToxipexGX with Mad Bull, still just one DCE... forcing you to set up again.
So if you can't have Toxipex up front, what are you running with it as the body?
Hopefully it's not something you have to set up... or else your Toxipex is going to take even longer to be effective.
Do not forget, there are ways to remove Poison, and ways to prevent Poison; thus doing no damage at all.
Best case scenarios are not how TCGs work. It's about consistency.
