mtg bloomburrow showcase cards Secret Lair: Drop Series The Gathering Starfall Invocation (Showcase) [Bloomburrow]

3 Serras Sanctum Rare - $226.47 Much like Tolarian Academy, Serras Sanctum is a land wholly dedicated to the production of mana, but with two key differences

This card has to be explained just a little bit

Ardent Plea is just as lowly costed as Shardless Agent (there are no cascade cards that cost less than 3 CMC), and it also gives you the Exalted ability

Mortuary Mire, Witch's Cottage, and Haunted Crossroads can be part of game-winning sacrifice engines, and putting such easy recursion on a land just asks for trouble

Very cool misprints, but Id be stunned to see them sell for mid-high 4 figures like a nice Alpha Shivan would
