Archlord Zerato Decks are kinda hard to run. Like Mazera DeVille, Zerato has a game-breaking effect...it's a continuous Raigeki as long as you discard Light monsters from your hand. I prefer Mazera's effect though...discarding 3 cards from the opponent's hand is DEADLY at ANY time, whereas Raigeki will just set the opponent back for a little while.
So, you know what this means. We have to overstock on Light monsters. I don't know too much about Sanctuary in the Sky decks(which is why the SITS Deck isn't complete on this website) but Light monsters I can deal with. We'll throw in two Airknights because they can be discarded and revived, DD Warrior Lady and Shining Angel because they're good Light monsters, and Mercury.
Most people don't put Mercury in Sanctuary in the Sky decks(that much I know) because it's effect isn't that great. However, I believe that it would work nicely in this deck...Zerato food, and if you summon it then you can replenish your hand. Test it out, because I know Mercury is not widely used by Angel users.
