@JamesMuddyGuardians will be custom, and you can create up to 3 balanced custom cards for your personal use in addition to it(though if it's for plot reasons, like, say, a disciple/mentor of one character giving the other a gift as a means of strengthening their bonds or some such example, I'll allow additional customs, within reason, of course).
Anyways, it seems like a sort of mixed reception toward Links, so here's a compromise(whether you guys accept it or not is fine with me either way):
No Link Monsters, but the new ruleset is still in play, sans the 12000 Life Points(debating on anime style 4000 or traditional 8000), which means:
-There are now two monster zone categories: Main and Extra. 5 main deck monster zones, as usual, but 2 extra deck monster zones, which each player can only have 1 of their Extra Deck monsters in at a time.
-Each player can only have one Extra Deck Monster on the field, and said monster goes to the Extra Monster Zone. However, and this is a homebrew rule, if the ED monster is Special Summoned
without using its respective summoning method, it goes to the Main Monster Zone. Which means stuff like Ultimaya Tzolkin and Utopia Kaiser(which is still kinda unplayable, sadly) can still use their Special Summoning effects without any problems, but Pendulum Monsters summoned from the ED still hit the field one at a time. Additionally, Instant Fusion treats the summon as a Fusion Summon, so the monster still goes to the Extra Monster Zone.
-The Pendulum Zones are in the same row as Spell and Trap Cards, and can be used as such. Which means that Pendulum Monsters can be set in the Pendulum Zones now, but are not treated as being in the Pendulum Zone unless they are face-up.
If I'm forgetting anything, please remind me. Thanks.
