SSSS( Stone Scar Sacrifice Shrine)

Love the deck, and after playing with it for a while, I think you should change out Seat of Chaos for Diplomatic Seal. I'm actually not sure why people don't play D.Seal over Seats in most decks. Pulling a depleted power can ruin an entire turn, and the color requirements aren't high enough for this deck to avoid it. Try running Diplomatic Seal over Seats and I think you'll really come to appreciate how they smooth turns out.
The following changes are just input from my experience. I'd love to hear your take. While Quarry is cute, it's only replacing itself. If it finds a 3 cost spell, it actually just made that spell 4 cost while costing you time. Incidentally filling the graveyard with creatures isn't nearly enough upside. You have two fantastic card draw engines already. I replaced it with Combust, because spot removal can be critical against decks that rely on a unit that doesn't interact. Things like Katra.
Fire Conjuring at x3 is a bit much I think. I'm running x2 and testing other cards for the missing slot. 1 copy of Granite Ring isn't horrible, but it is clunky. It synergizes with Rat Cage and Torrent of Spiders. I tried a copy of Cabal Repeater, and found it really lacking. In theory it would help solve board stalls. In practice, it sits around while you do better things. Assembly Line might be nice, but I haven't tested it.
