This is a pure red-eyes deck with a hermos side deck for fun. If you are playing casually I recommend siding in Hermos (or side him in whenever you want).
if you don't draw Red-Eyes fusion there is still a way to get Red-Eyes Dark Dragoon on the field; Predaplant verte anaconda. Just pay 2000LP, send Red-Eyes fusion, DM and REBD to the grave. It's not easy to get Anaconda on the field as you need 2 monsters to link summon it, but its still a decent back-up plan if you don't draw Red-Eyes Fusion.
Main Deck and
Side Deck (40 cards) (15 cards)
I put more monsters than spells/traps mainly because the Red-Eyes archetype has many monsters but not too many good spells/traps. This deck is also gemini, so say hello to Phoenix Gearfried! Gemini ablation is for getting Red-Eyes Black Flare Dragon and Phoenix Gearfried on the field (as well as the other gemini's). Gemini summoner is for when you can't fusion summon but you have a powerful gemini card in your hand.
8x Fusion cards: Claw of Hermos x3 (In the side deck), 3x Red-Eyes Fusion and 2x Polymerization for fusion summoning the fusion dragon cards.
I added 3x Ash Blossom (side deck) and 2x Ghost Ogre because I couldn't find enough spells/traps, so instead I chose handtraps. Luckily Ghost Ogre is quite reliable.
Extra deck (9 cards but 4 cards in the side-deck)
The extra deck contains powerful cards which are part of the Red-Eyes archetype. Clearwing is just for taking full advantage of the handtraps (the handtraps are tuners).
