Lockmaw

Pearlmaw Lockdown is a control deck that aims to remove the opponent's threads and stall until it can win with its inevitability package. It is the kind of list that wishes to play like a "turbo fog" and eventually prison the opponent (in terms of mtg archetypes).

Here the actual win-con is scaling, but it could any that doesn't require interacting with enemy units. Right now, Spire of Edenhold seems like it could work wonders with this.

This particular list is overly polarized on purpose, but some toned down lists that don't go all-in in this one tactic have seen some success on leaderboard.
