After tons of attempts i managed to beat the challenge by playing Life Cost 0. It ia very risky however since you have to start the duel with 1000 or lower LP, get the Heads Coinflip AND have to get cyber stein in hand. Once you have the combo you can lock him down and recover using neo spacian air hummingbird and start counter trapping your own cards
the SRs and the URs are not necessary.
key cards are 3 golden ladybugs and 3 ultimate provision. You can discard a golden ladybug to negate its OWN effect. Use the 3 Skystarray to slowly kill him. The rest of the deck just add stall cards or LP regen cards like floodgates.
Temple of the minds eye is useful too
Legit would have finished by now but been pranked twice now, apparently using a token ruins the win only using DARK monsters, even though the token was dark...
The regular floor enemies are manageable.
DD Trainer is the obnoxious one whenever he butts in. Always seems to start with Dimensional Fissure to screw decks like Aromage and Aliens, Soul Exchange and DD Warrior Lady for removal and DD Survivor constantly returning to the field when Fissure is active
