A very clever thing we should take into account is the region separation in the "Original" Inscryption game.
Leshy and Grimoria are on the western side, while Po3 and Magnificus are on the eastern side, and are permanently divided from one another by a broken bridge unless the player progresses with the story.
This division is also Thematic of course.
The eastern side is about the Cycle of Life and Death. Leshy deals in Blood, Grimoria in Bones. Once Leshy is Game Master, is Grimoria's mechanic the one he incorporates into his game, not just because he's slower at adapting mechanics or because of Flavour (Robots would be Ill fitting for the dark frontier folk tale he's trying to spin, and magic would damage the "realism" of it), but because that's the one Scribe he's been closer with.
At the same time, the western side is about Magic Vs Science. Po3, once it becomes Game Master, only incorporates Magnificus' gems mechanics into his game, while Bones and Blood are completely forgotten about. This is not due to Flavour as you might think it was Leshy's case, since Po3 cares more about the mechanics of its game than its lore, but because, again, Magnificus is his closest scribe.
However, both games, while relatively complete as themselves, still Lack something. If you play the "original" game of Inscryption, you'll notice how all 4 mechanics complement each other, both via the use of "Hybrid Cards," cards from one Scribe that however work well with another, and Via a simple gameplay loop.
This to say, the western cards are fodder, the eastern cards are to be fed.
Energy Cards work on a Hearthstone system of mana. You get 1 to 6 energy per turn, and play them as is. This means those cards can't be all that good or it would create a power imbalance. Case in point, their "Guard Dog" card (2/3, Moves to block the last summoned enemy creature) costs 6 out of 6 mana, the full extent of their range.
Blood Cards are, on the other hand, Tribute Cards from Yu-Gi-Oh. They are relatively strong given the fact they require one or more sacrifices to be played. Their Guard Dog card therefore requires 2 Tributes, which becomes incredibly easy if you can use any other scribe cards to sacrifice for it, but is also quite prohibitive to pull off without Squirrel Tokens.
Magic Cards have a surprisingly close affinity to Magic the gathering's lands. You draw Gem Mox Cards (lands), and you drop them on the field, and that gives you the colored mana to play cards of the appropriate colour. Most of their cards therefore are incredibly dependant on Mox Cards being alive in the field, and are also stat and effect wise pretty weak unless you get a perfect board. Case in point, they lack a "Guard Dog" card.
Bone Cards are based on a death token structure, which means you can virtually play nothing in the early game unless you have some of the weaker bone engines and then sack them. However, Bone Tokens are also incredibly easy to get under the right comp, both in Leshy's game, and in Inscryption proper, so their power, while not as weak as an Energy or Magic Card, is still weaker than a blood card. Case in point, their "Guard Dog" card costs 7 bones, which is pretty much 2 +4 Bones on death cards.
All 4 mechanics synergize with one another. The game is, therefore, incomplete unless all 4 Scribes are working together to give the player a good experience.
Because that's what ultimately they all want to do.
Leshy "kills" you and has you gauge your teeth and eye out not because he wants you to suffer. He knows this is a Videogame, he's not harming you, he's giving you an "experience," a creepy game with mysterious vibes and all that shit. He wants to spook you, and he wants to entertain you, and you realize this not just in your final, final battle with him, the no stakes game as the world is deleted, when he congratulates you for being a great player, and for all the experiences you've had with him, but in the very second you grab his camera and "Betray" him, with him getting, for the first time perhaps and not just for show, Genuinely angry at you, calling you an "Ingrate" after "All the things I've done for you."
Po3? He wants to create a mechanically challenging game, one that will be played by millions of people. Yes, he highjacked your computer to send his game through the internet, but he's doing this out of sheer self preservation, out of a desire to be played with, not just by you, but by everyone.
Grimoria herself, despite starting the deletion, also laments the fact she would have loved playing with you as game master. She also desired making a game, one to entertain you, and the only reason why she's not doing that? It's because there's OLD_DATA slumbering at the bottom of Inscryption, and she realizes that it needs to be erased, least something terrible happens.
Magnificus? With all his theatrics and abuse on his students? He didn't just wanted to create a game, one with him as the villain, the most overtly villainous of the 4 Scribes in the "original" game. He wanted to give you a show. He wanted grand battles on pillars with dueling disks, shadow games, anime shit. He wanted Drama. His methods were terrible and monstrous, yes, but they also worked. The Blob Disciple managed to survive TWO takeovers as a living being in the game room, not just as a prop on the game board or as a puppet for the game master. The Sensory Deprivation Disciple goes absolutely insane due to its torture, yet is also the ONE thing that survives both the game wipe and the destruction of the Disk, because he's used to work with nothing.
They all just want you to have a good time. They should just eat up their egos, and work together to achieve this.
Unfortunately, they don't realize it until it's too late.
