I currently like Jeskai as an archetype better than Grixis in this metagame, but this is due to Path to Exile being miles better than Terminate in this over-saturated aggressive context. Goblin Dark-Dwellers really doesn’t fit into that type of strategy (eight one-drop removal spells) which is what I’m going after if I’m pursuing Jeskai.

You can definitely play Goblin-Dark Dwellers alongside these spells, I’ve just found that having a Kolaghan’s Command or something in the graveyard as a “fail-state” for when we haven’t found Ancestral Vision to give us options. Jeskai tends to be pretty creature light, but maybe the creature heavy versions that play Restoration Angel wouldn’t mind playing one of him.

Really, in that slot Sphinx’s Revelation might play nicer with the rest of your deck, but they’re close enough that I think you’d be fine going either way. Try it out and tell me what you think!
