That's why things like Goat format exist, to just stick to older cards. Edison has synchros, but is still in the earlier portions of when the game sped up.
The new Genesis format also cuts out Links/Pendulums for a good chunk of bullshit.

As for where, Duelingbook would be my suggestion. It's not the best, but there's a decent chunk of people playing Goat/Edison and other niche formats there.

You play Reaper, retard.

You clearly don't actually play the game because the two strongest engines in recent metas has been two Fusion setups (Dracotail and Branded as of BPRO, both of which are run together) and one Ritual setup (Mitsurugi). K9 has also been strong, but it pales in comparison to the things that those two engines do.

You cannot have what you want if you keep drawing false equivalences between the erosion of card design over the years and the presence of summoning mechanics that were introduced a decade ago (if not longer). Every single summoning mechanic is fair and balanced at their base, but the humanzees at Konami can't help themselves and feel the need to make it so every new powerhouse archetype does their best to get around those mechanics.

>What if we made trap cards for Maliss that cheat out high-level Link monsters for link climbing
>What if we made the entirety of Regenesis special summonable without tribute, as long as numbers exist
>What if we made it so that these Fusion materials can come from anywhere and move to any location
>What if we made the entirety of Dracotail?

Ironically, the only summoning mechanic that ISN'T consistently cheated is Pendulum Summoning.

If you can live with XYZ and Synchro, Genesis is a new and prolific format that assigns every card a point total, with your deck having a maximum of 100 points, and doesn't allow Pendulum or Link monsters. There's no associated banlist, so you can play cards like Pot of Greed, but most of the cards like that are heavily pointed.
The point total list also updates fairly often, as they course correct to make every floodgate and format-defining card at 100.
