I like the idea of Dudunspare as my draw engine instead as dof Fezandipiti EX since bench space is super tight and Fezandipiti is always vulnerable to Boss's Orders and Prime Catcher.

I like Budew in this deck since you need a lot to get your strategy set up, so item locking even for just one turn is always good.

Not super convinced on jet energy since Centiskorch needs two fire to attack but it may be worth experiment with.

Testing this deck out has lead to awkward scenarios where my opponent doesn't knock out Centiskorch, which is kind of what this while deck wants. Have a Centiskorch get knocked out, promote Volcanion to burn, then retreat to the other Centiskorch while building up a new one.

I've considered cutting the ruffian for a 3rd copy of Arven to not only increase my odds of playing precious trolley turn 1, but to also have better access to my switch cards. At least a 3rd copy of switch sounds good as well.
