It get's to run a lot of high CMC tutors and interesting cards not found in other black cEDH decks thanks to K'rrik's unique form of "mana ramp"
Over the past week I've been pondering over a Cryptolith Rite-style archetype, especially with Katilda, Dawnhart Prime making its debut in MID (and later remembering that Earthcraft exists)
Second of all, its among the cheapest cards that have this ability, which gives you a lot more +1/+1 counters in the third, fourth, and fifth turns, when you would be waiting for other bodies to come online
Mendicant Core, Guidelight Mendicant Core, Guidelight is an interesting aggressive artifact creature thats bolstered by other artifacts you control
Speed : How little pilots must wait before the card comes online
This is the sort of worry that can be relieved by seeing basically anything on the Modern, Legacy, or EDH format staples list at any rarity
