I prefer the more resilient versions for several reasons. Though I haven't been able to join as many Dailies this month as I was in May, June, and July, I had a lot of success then with lists that walked the line between Paradoxical control and Cantrip Gush-Delve.
The main reasons I've preferred the Paradox lists with a Mentor win-con that are not "Opal Soup" are:Lower frequency of hideous mulligans. Less games auto-lost due to inactive Mox Opal(s). Better equipped to win despite Stony Silence/Null Rod. Monastery Mentor is the best answer to Monastery Mentor Able to change roles, particularly post sideboard. For instance, when an opponent can be expected to overboard v. Paradox with Null Rods and artifact hate, I board out Mana Vault, sometimes EE, and 1 or 2 Outcomes, morphing into more of a straight up Mentor deck. Paradoxical Mirrors. The control/resilient versions have been substantially more favorable in matches v. the combo lists.
