Notes & Combos
I was able to hit DLv Max with ShiningSarc-Kasthira-Fiendsmith SlopPile deck. However, jokes aside, I do believe there are some interesting synergies between the engines here.
Let's be honest Shining sarc is not a very good deck, it has a very low ceiling going first and dies to a single interrumption. Here's where Kasth and Fiendsmith help, both engines are basically handtrap magnets which allows your shining sarc plays to resolve.
And we want them to resolve because there are 2 very good things SS deck has. Gandora G and turn silence.
Gandora g board breaking abilities are excellent going 2nd or on your 3rd turn. Just let the opponent waste all their negates on your other engines, then get Gandora-G on the field, wipe and banish everything and swing for game, it can also be pretty unexpected for your opp if you have managed to hide your shining sarc plays until the last possible moment. As shining sarc cannot be destroyed by monster effects, it has a lot of chances in at least getting Gandora on the field.
On the other hand turn silence can really helps as almost nobody remembers the graveyard effect to stop the battle phase. Which, for whatever reason, your pitty gadget on the field seems to act like a magnet for first attack.
This deck has a somewhat weak going first play, you usually endup on caesar with gadget and turn silence on the field, lacrima in gy for paradise, and ideally a kasthira monster + hantraps, but this is usually enough to survive one turn.
The going second for this deck is actually very good, you have superpoly, TTT, fenrir and gandora to break boards and you have fiendsmith to bait interruptions and swing for game with Agnumday and Lacrima burn.
I would recommend this deck to everyone, is actually very fun to play and requires a lot of thought as your turn 1 or 2 plays will vary depending on what cards you have drawn.
Replays
Here are a few replays of the deck, I recommend the 2 older ones as you can see better how the engines collaborate to break boards.

I also added my rank up replay against crystron where I misplayed heavily but still was able to win with the preassure of Fiendsmith and SS.
