Shrines are back!
There haven't been any new shrine enchantments since the Kamigawa block, and now we have six new shrines to make a new shrine deck for commander.
The best commander for the shrine deck would be Sisay, Weatherlight Captain. Her activated ability can search your deck for all 11 shrines and put them on board consecutively.
When you have all the shrines, you basically win the game, so the value of Sanctum of All is practically unbeatable.
