Given how many people find these two cards to homogenize and reduce fun in the format, but you are unwilling to take steps to ban them. I would like to suggest instead you split the queue system. If players do not put FotD/Ugin in their deck they should be matched against other players who do not have those cards.

This would allow the people who want to do try hard ultra-competitive HB play against each other, and the rest of us who want to play for casual fun can explore strategies that do not revolve around those two cards the way that most of HB does at the moment.

You should also consider taking action over Paradox Engine, there's a reason that's banned in EDH.
