I thought Mythic was full of jank players?

A few days ago I made it into Mythic for only the second time ever (yay!).

I thought once I got there I could swap to some jank decks and have fun, things like land destruction or All Will Be One / Temur Overlords combo ... But no dice, I just keep running into the same meta that I had to grind through in Platinum and Diamond. It's Esper Pixies Discard, it's Mono Black ... Thankfully there is definitely less Mono Red Aggro.

Wasn't the theory that once most people hit Mythic they just went jank to enjoy games?
