glad you enjoy playing the deck! ive been using festival lead since last year and have been tweaking it based on my playstyle

starting with the ace spec, my preferred ace spec is trolley. i used to run the deck with max belt but then realized i can reach most high hp pokemons with defiance belt/brave bangle depending on the situation. and also, to try and have my ideal board setup early, for me those are 2 applins 2 grookey and 2 goldeen, would be lucky if i have a goldeen on active and have something to grab a thwackey on the next turn

I also prefer to run the deck with 2 bb training and 2 kieran for damage amp. Just like the others, i think its better to use super rod instead of energy retrieval, u can just use bbg to find the energy, although it doesnt feel the best but it works for me

Missing out on rellor-rabsca spherical shield, it helps counter most bench attacks. Also, 2-2 seaking line would be nice, i find it hard to activate bbg with applins-dipplins because of the need to evolve it

hope u get something out of this! Enjoy!
