People on reddit and sourcing this thread as the start of ultra modern.

No it's just a name change.

Regardless it didn't take off until here. So well done it making the name stick and get people playing it. I'd say it was more down the card pool growth more than anything.

If this happens, it'll be starting at Origins and it'll extend from the Era of the Gatewatch to the beginning of whatever the next Shtick is.

Alternatively it'll start at Return to Ravnica as the start of the "Look now we revisit places constantly!" era.
