Underworld Breach, Wrenn and Six, 3eferi, Oko, Veil of Summer, but most egregiously the Companions are a breaking point.

Magic is power creeping too damn much and too damn fast. Defeats the point of an eternal format if you have to revamp or outright scrap your deck for a new meta every month. Companions completely change the nature of deck building itself and unless they ban all companions and promise not to print any more, I see no reason to continue with legacy, modern or pioneer.

My friends and I decided to leave legacy for a version of legacy before WoTC ramped power creep to 11. We are leaning towards jumping into Legacy as it was right before War of the Spark released as this allows for the largest number of cards while leaving most of worst mistakes of recent set design behind.

Is anyone else here making the switch? If not, is there an alternate format that you prefer? I heard mention of a preInnistrad format so if you think thats a better format, you can sell us on that.
