Any suggestions are welcome
Toxicroak ex i don't think will ever be good, but there are ways you can make it functional for a casual locals deck. Charging it with energy is the most difficult part. Even with a dark patch and double turbo, it can be clunky trying to get three energies into play to attack. Even when everything is going perfectly the damage maxes out to 200 damage. Still, it is very cheap and the individual cards are a lot easier to find in bulk binders. Salvatore is a good include since it allows you to attack turn 1 going second.
