This is a quirky take on True Exodia, aiming to go first and FTK with it on Dueling Nexus. Win rate is probably about 30% just owing to whether you get the few necessary cards to win.
This deck has virtually no counter play capabilities in favor of trying to max out the chance of doing the FTK, so if the opponent goes first and manages to throw a couple of monsters out, you're probably already done for. You can try throwing in some lightning storms if you want to counteract this; just be careful not to brick yourself with too many counters.
The side deck is just full of random cards that didn't make the cut in my mind, though tri-wight has high potential, just doesn't come out consistently.
For those unaware, the FTK is to send a bunch of spell cards to the graveyard. Use Shien's Spy to give your opponent True Exodia. Then use Treasure Panda to bring out the 4 pieces of exodia in the deck and a link-2 monster. Use Treasue Panda and the Link-2 to make Knightmare Unicorn, then use it's effect on itself. And with that, you win via the effect of True Exodia. Sounds simple, but is really just pure RNG.
