Dragons and Egyptian Mythololgy, 2 awesome things rolled into one. Add aliens and you have... well, whatever this deck is. It uses the Hieroglyph Engine to beat face, and can summon Neo Galaxy-Eyes quite well.
Hieroglyph Seal - Staple, you'd be stupid not to run it in this kind of deck.
Tri-Horn - A good Level 8 and a DARK.
Wattmeter-Dragon - This + Shu = an instant Atum
Apocralyph - Put needed monsters back in my hand for another go around, remove for redmd
Galaxy-Eyes - Great card, who gets his points back if summoned by Atum simply by using his own effect
Geb - Awesome card, beat over lower monsters or sac for Shu. Either gets me another monster.
Shu - Amazing. Special off of Tefnut, get a monster, sac a Geb or another Tefnut, get another monster, make Atum. Great stuff all around.
Tefnut - Tribute and REDMD fodder plus a recruiter.
Honest - In a Deck of LIGHT Monsters, who else?
Lightpulsar - that extra bit of muscle if I need to beat face more, or make a Rank 6.
REDMD - Staple in Dragons
Spells are almost all staples in this kind of deck. Lance can either save my monster from death or make Geb beat over an enemy to recruit. Trade-In is a must with this many Level 8s, and Super Rejuvenation is as good as Maxx C for draw power.
Side Deck is for experimentation. Alexandrite Dragon lets Geb make a Rank 4 in a snap (if I ran any, that's for another test). Nephthys is a good counterpart to Shu in a Monster-heavy match, a second Lightpulsar if needed, and Maxx C as a staple. White Elephant's Gift works well with the normals, and Photon Sanctuary is likely leaving soon. Shadow-Imprisoning really only hurts REDMD, but as a side against Inzektors, Dark World and a couple other decks it's devastating.
Extra is pretty standard. Five-Headed was back when I had Future Fusion and Dragon's Mirror Sided; i can likely make another build to use him better. Gaia Traguno turns a used Atum into a piercer for massive damage, and the deck swarms so hard there's no point in running just 1. Gustaph Max makes for a little extra damage as needed with 2 REDMDs (not hard), Trip Atum and Ennead are staples, and 1 Neo Galaxy-Eyes doesn't hurt too much but comes out when needed. Focus Force is just a beater, as is Streak Bouncer (but better against, say, Wind-Ups). Ptolemys is boss, and Thunder-End does Ennead's job better if I need an OTK.
And if any proof is needed...
As always, open to suggestions but ONLY if justified.
