Graboid + RT was gonna be very strong, especially since RT and BB could take down the most obvious deck (NT Pillars). Modified it a bit after each match to optimize, final version turned out to be very simple:

I was afraid the meta would become too stale as defensive options were too weak (which would lead to domins facing off in an attempt to get lucky and win). Thankfully it wasn't that horrible, with hope being available. Still would like to see less restrictions next time, as it does push too hard in fixed directions.
