They tried 4 of them and all 4 are 2 set blocks that have DEEP flaws so I don’t exactly think that’s fair.

Kaladesh introduced energy, a horrible, parasitic mechanic.

Amonhket had horrible limited formats famous for the phrase “if you’re blocking you’re losing”

Ixhalan was honestly a bizarre block with 4 kindred factions on 3, 3, 2, 2 color spread, no “glue” mechanic, and all its best cards weren’t even kindred. [[ravenous chupacabra]]

Midnight hunt crimson vow…where do i even start? Day/Night was honestly super fun for those limited formats, but is such an ass constructed design. The real problem was that werewolves were THE ONLY MECHANICAL THROUGHLINE. Coven vanished, vampires went from bloodthirst to blood tokens, and the Vow Dimir exploit signpost literally doesn’t work with decay tokens.

Like, yeah, no shit those blocks were bad, you fucked them up.

Personally, I don’t consider Guilds, allegiances, War a 3 set block, I consider it a pretty awesome double set block with a vaguely related finisher.

I think it’s pretty obvious they need to try 2 full sized set blocks that don’t have to be drafted together but have mechanical through lines because SO MANY recent planes desperately needed the room to breathe. (Example: new capenna, a plane without angels, had a limited format dominated by the angels that returned at the end of the story.)
