Bear with me as I segue completely into something NOT Duelyst to illustrate my suggestion.
The Elder Scrolls: Legends features a solo iteration of Gauntlet that has quickly become my go-to mode for progression/card collecting and casual play. And since AI games can be interrupted and resumed at any time, it’s also my default mode when there really isn’t time to play but play I do regardless, and during those long deep orbit debacles, polar perils, and other spotty connection scenarios which would have me ostracized from the community before too long.
You can read more about the implications and my unbridled passion for this mode in this Reddit thread. But in short, the ticket and drafting processes function exactly like a regular arena (TESL’s Gauntlet analogy). But instead of random players, you’ve a choice of 8 AI opponents (drawn from a large pool of pre-constructed decks), some of which might also bring with them permutations to rules or circumstances (often advantageous to the AI, but not always). If you defeat all 8, you face a boss, and victory will improve your solo arena rank and offer greater resistance next run.
And it is just TONS of lots of fun. Which is not bad, considering that it is also a great way to familiarize yourself with cards, combos and fundamental strategies, build up skills, and grow your collection.
In the end, we’re all here to go (real) face. But the wonderfully exciting tension and focus of multiplayer is not always desireable (for reasons of data loss, convenience or confusion). A solo Gauntlet would offer an alternative to versus play that - unlike challenges and practice - is not limited in progression and rewards, and neither in challenge and variety.
Challenging and interesting AI play that also offers unlimited progression is just about the only thing I miss in Duelyst, next to mobile support. While downright idea thef… uhm, homage is beneath the innovative minds of Counterplay, I hope something at least distantly related to TESL’s solo arena might find its way across the realms to Mythron.
But dressed up and resplendid in all its pixelated murderous minitiature glory, of course.
