Good eye, indeed that might make people think a Comeback Victory duel assessment bonus might be possible. With this deck you need to keep Antinomy's monsters in face-up Attack position on your last turn, and your Ra to have at least 10k attack points more than at least the weakest opposing monster
Have u tried adding Giant Trunade? And Good Goblin Housekeeping to increase deck milling power. It's okay to have 1 or 2 cards more than the 20-card minimum, cos the milling will still take u at least 4 cards faster than Antinomy.
