I found that because of all the mythics and rares I had many more high mana cards than usual. Sometimes my opening hand was like I have no idea what to do with this until turn 4 or 5.

Then again is does kind of level the playing field as not to have people over reliant on getting that one powerful card that can swing the game in their favour.

Being "silly" though, in the future I would consider offering more mulligans for midweek events. We're all using a deck we have no experience with so if there's less reading all your cards to figure out if you've got a playable hand or not and keeping the game moving that's a good thing.

Those were some of the slowest games I've ever played where we're both reading each other's cards because there's potentially a lot of interactions. Fun though if you're patent enough and a real learning experience. I might not offer a mulligan for pauper, but would for this because cards of these rarities are less straightforward like this is just a creature that attacks and blocks.
