Thoughts on what changes they can make to Sanctum going forward?

Sanctum was fun for probably two days and the grind is just terrible. I wouldn't grind as much, but the rewards for this mode are actually pretty decent and I'm a sucker for borders.

I really hope they make some changes if this mode comes back to where we're not playing against the same deck every single match. I think I've played 200+ games of Sanctum and 175 or more of those games were against the same Guardians deck. It's just zero fun. Are there any changes you guys would make with this mode for next time? With the way this game mode is set up, I don't think there's much they could honestly do to make it to where there's not 1 or 2 oppressive decks that are just infinitely better than the rest.
