I have found what may officially be the most broken team in the game. SO fiddly, SO gimmicky, but utterly and completely broken.
Team (in turn order)
Guise (Base)
Covert Funding Wraith
Team Leader Tachyon
Accompaniment Argent Adept (prime wardens)
Lifeline (any)
Guise and Wraith both use covert funding. Congratulations! By passing their draws back and forth you can now cycle through their decks and pull every card you want (for your hand -1 cards) EVERY TIME EITHER OF THEM DRAWS. This means you can get both Best Cards and anything else you want every time you have a draw.
Team Leader Tachon feeds cards to Wraith and Guise, who can then cycle any cards they want, then pass the extra draws to anyone who needs them letting the rest of the combo get set up.
Get the argent adept+lifeline convergent (that means it's not infinite) recursive combo up:
Argent Adept with Inspring supertonic gives plays to Lifeline
Lifeline can spend plays on Repair Leyline to give power usages back to Argent Adept, and gain a repeatable "Team Leader Tachyon" style draw and a heal everyone 1 for doing it. Use Calculated Action and Harrowing memories for extra absurdity (Once you draw out Lifelines deck [and you will] you can reliably heal everyone for X and give everyone X cards where X is between 4 and 11 [depending on how clever and lucky you are] each time LIfeline can get a play from Argent Adept [you can do this multiple times within the same turn])
This combo also spins off a few excess power usages (letting Guise activate his power to play best card ever, and chain it to a triple Retcon whenever you need)
Hit the Nitro:
Make sure Argent Adept has
- Inspiring supertonic
- Sarabande of Destruction
- Akpunku's Drum
Kawaii now lets Guise, on each hero turn, use "Lemme see that" on Drum to pass a play to lifeline to trigger the recursive combo. EVERY SINGLE HERO TURN. Make sure Guise uses the final melody from drum to kill "Lemme see that" so you can use it again next hero turn.
Mix in Extreeme, Barbarian, and anything else you can find room for (remember you can pick every card you want each time either wraith or guise gets a draw)
Congrats, you now have 2 hour long hero turns. GEE GEE LEGASEE!
