Sanctum of All
Legendary Enchantment — Shrinerare
At the beginning of your upkeep, you may search your library and/or graveyard for a Shrine card and put it onto the battlefield. If you search your library this way, shuffle.
If an ability of another Shrine you control triggers while you control six or more Shrines, that ability triggers an additional time.
