It's an amazing deck in this Tryout Duel - 30 Second event where speed and efficiency are rewarded. The Horus cards quickly build multi-layered, destruction-resistant boards and the Eldlich cards provide great discard fodder for King's Sarcophagus because they have graveyard effects.
Some Tips
Hapi, Guidance of Horus and Qebehsenuef, Protection of Horus are your main defenders for when your board gets broken. Qebehsenuef's trigger effect is critical for protecting your Horus monsters from attacks and targeting effects like those from S:P Little Knight, Chaos Angel, and the True Draco cards. Hapi's trigger effect punishes the opponent's sloppy plays by recycling resources from your graveyard, but it can also be used to disrupt your opponent's graveyard.
Solemn Judgment is your best defense against Harpie's Feather Duster and the uncommon, non-destructive board breakers like Evenly Matched, Dark Ruler No More, and Book of Eclipse. For more protection against these cards, Lost Wind can be replaced with Iron Thunder, but it's not necessary in this casual event.
