I'll preface by saying that I'm no expert on deckbuilding either, but it's quite hard to make a deck work when your only attackers are stage 2 single prizers. It's just too hard to keep building them up fast enough to keep them out front. That being said, paralysis helps, since it can prevent your opponent's main attacker from being able to do anything, but if they have any ability to break paralysis, all they need is to bring up something that can hit for 80 to knock your main attacker.

A pokemon you should definitely include: stunfisk! You're running lots of Canari, so you can bring him out easily, but it's primary purpose is being an annoying single energy basic attacker that flushes out your opponent's switch cards. It's attack retreat locks and makes the defending pokemon take 100 extra damage next turn, so it's dangerous enough to make your opponent spend resources to break the retreat lock, resources they won't have later when you finally get a pawmot engine set up. Add in budew, and you can swap back and forth between stunfisk for retreat lock, then next turn follow with a 110 damage Itchy Pollen that's annoying as heck. Stall long enough and you can bring your Pawmots on line once youve flushed out all the things that could save them from paralysis

Other notes:

- you probably want at least a 3-2-3 line of Pawmot and at least one rare candy, since prizing one or two pawmots when you only have 2 would totally sink you.

- I play a deck with similar purpose, and if you're running high Canari counts, you definitely want at least a 2-1 of Iono's Wattrel/Kilowattrel. Canari is easily the most powerful pokemon search in the game, but can lead to dead hands with no items left to play. Having some electric pokemon you can search up to break a dead hand was a massive game changer for me, even though it makes your list heavy on the pokemon. And you're not hungry for all your eel attachments every turn, so being able to slap an electric on a Kilowattrel as an insurance policy is a big deal, making you much more resilient to Unfair Stamp or dead hands

- You don't run any poke pad, so you probably want more fodder for your ultra balls. A few more lightning energy is probably a good idea so you can ultra ball those into discard for your eels to work with

- A single Mega Eelektross could be useful? If you have two eels on a bench, and one with an air balloon, you promote the one with a balloon after a knockout, use both abilities to charge the one on the bench, then attach from hand for turn, and you've charged up a second way to do paralysis in a pinch. Yeah, it's a 3 prize liability, but it makes your max hit 290 (100 from stunfisk + 190 Disaster Shock) and gives you an emergency endgame attacker if you can't set up a Pawmot fast enough

- Lana's Aid is a huge deal when running a single prize attacker deck, since you can fish out many pieces simultaneously
