[All cards at base rarity to make importing easier]
Do you like Tinkaton's big damager from having a big hand? Or how about Espathra's big damage from punishing opponents loaded with energy? Well, it turns out you can have both at once! Using Xatu, you can stock up energy on Espathra EX while making your hand bigger for Tinkaton for a delicious wombo combo. Hero's Cape can either bulk up Espathra to help it take hits, or put it on Tinkaton to make your opponents suffer even more. Gholdengo is there for draw power, and can be replaced with other draw cards. I don't recommend Bibarell, since you want to have a hand larger than five.
Ideal start is Tinkatink up front, Flittle and as many of your Natu on the bench. Get an energy on Tink to use collect, and if you can get Jacq or Arezu, evolve your Flittle into Espathra EX and your Natus into Xatus. I tend to get Espathra built up a decent amount before my first Tink gets knocked out, so I switch that end and start building a second Tink on my bench.
This is by no means a perfect deck, but it's fun to play and oh so satisfying when it goes right. Feel free to suggest tweaks in the comments! I'm not particularly experienced, so I'd love to hear more improvements.
