Anyway, back in the old days some LED builds used to play Tireless Tribe as a sideboard replacement for the artifact; now there's Faithless Looting, so Deep Analysis has been obsoleted. Both Tribe and Looting can only be cast via rainbow lands, while Looting doesn't eat removal and has an utility in the graveyard. During post-board games my LED-Less build (as many others do) packs a full set of Tribe/Imp/Study. This LED build has access to Looting/Imp/Study instead. The difference is abysmal - I can no longer grind games with Tribe, though I can find solutions while being more explosive with Looting. Swords to Plowshares is also more common than Spell Pierce. These are my assumptions, so please correct me if I'm wrong. Now: I thought of a pretty linear sb plan like -4 Breakthrough/-4 LED, +4 Grudge/Chain, +2 Tarnished Citadel, +2 Dread Return/Ingot Chewer (against Cage), with Iona taking the spot of 1x Ichorid if needed. My question is: is it viable? Thanks in advance.
