Notes & Combos
Climbed from M5 to M1 with this list. The Orcust and Horus cards provide more ways to bait handtraps before going into your actual plays. Horus cards are also great extenders and have strong board presence. Only conflict between them is not being able to summon the Horus monsters if you want to use Crescendo's GY effect.
Did not go into the Leo lines at all because I'm unfamiliar with them, but didn't miss any of the other extra deck options anyway.
