I personally run 2 Fenrir, 1 Riseheart (search target for Fenrir), 3 Unicorn, 1 Theosis, 1 Birth. Birth gives you 2 lvl 10 synchros, and Theosis is for when you've committed to the Kash side of things.
I also recommend running 3 copies of Instant Contact. It's a Water attr in grave, and it can become a lvl 5 or a lvl 7. Lvl 7 can also assist the Kash side plays
For ED, I run 1 Shangri, 1 Ariseheart, 1 Big Eye, 1 Zeus. Big Eye doesn't appear that much though, and you can always just trade him for another Synchro.
That's my personal preference though, cuz PUNK Kash is very hand dependent on what you end up doing.
PUNK board looks like a lvl 8 synchro + Sharakusai and 2-3 lvl 3 psychic tuners in the grave with 1-2 set pass. You chain Sharakusai on their turn and summon Amazing Dragon to do an AOE bounce back to their hand. If you have the field spell, you also get a draw here, and if they responded to Sharakusai and you have Dragon Drive in grave, you actually get 2 draws, which can draw into a hand trap or a setup for next turn. PEP pass is pretty unreliable, and yeah all pure PUNK routes are pretty weak to Kaijus and Lava Golems. If they imperm or Book of Moon Sharakusai, it's pretty bad too. If your lvl 8 synchro is an Adamancipator Dragite with Carp or a water HERO in grave, it's pretty good. Draco Berserker is also a decent alternative, Dragon Drive on field is not preferable but sometimes unavoidable
PUNK + Kash board looks like 2 lvl 10 synchros, and a Kash xyz, or a lvl 8 synchro + Sharakusai. You can do some really high roll mega crime with PUNK + Kash. You search Birth here with Unicorn instead of Theosis
Kash board is just your average Shangri and potentially Ariseheart or Unicorn/Fenrir on board. You can go Ariseheart solo if you have a lot of backrow and handtraps. Otherwise Shangri + Unicorn or Fenrir on board is probably as good.
For PUNK plays, you try to summon Sharakusai if you have a PUNK in hand or board after. You go into Carp and try to use its effect to summon Deer Note and Wa Gon. Use Wa Gon to search the field spell. If you already have the field or Wa Gon in hand, you search Madame Spider instead and search the trap (the negate one is better for non-pure PUNKs, for pure PUNKs, run the destroy one).
Ze Amin and Foxy Tune and Ogre Dance are routes to get you to that exact play. If you play your cards right, they're basically 9 cards that get you there.
