Being a mana cheaper than Conjurers Closet does mean you lose the ability to steal creatures (they come back under their owners control, boo!), but its still great to have this card
We arent given percentages, so Im running with the idea that all are equal and with 163 options, over two slots, youve got a 1/81.5 of getting the specific EA you want
I also imagine a white-based aggro deck built around cards like History of Benalia and Venerated Loxodon should line up well against this deck, but I havent really seen that attempted (side note: Mutavault is probably better than Benalish Marshal)
It's here for a free discard that doesn't require mana or tapping, discard to trigger your leader, and then recur with haste what you discarded if a dork or cast something else instead
