Unfortunately, Boros cycling was a rather parasitic archetype. No other deck wanted the cycling payoffs, and many of the cycling cards were weak enough without payoffs that no other deck took those either. While it was one of my favorite archetypes, it was clear I had to say goodbye.
Luckily, the Boros artifact archetype has gotten a lot of help in the last few sets (and likely in future sets with the phyrexian stuff), and it has some good overlap with the Boros equipment deck, so I decided to give that a try. I'm looking forward to seeing how it performs.
