Did I try the deck out? Not in the slightest, I’m afraid, pure theorycrafting. I’m not sure I want to drop the thousand spirit on the visionars, I’ll probably wait and see what @deathsadvocate does with Starhorn in his new decklist, whenever that thing shows up. @fr0stfyre1 is right about the rancours, they should go in instead of the kujatas.
I have no idea if this deck would actually be much good or not, it really depends on how good visionars are or aren’t. They’re huge bruisers that only get bigger, and they’re still major threats after dispel, and they live through rebuke, but they’re still five-mana minions that do nothing the turn they’re summoned and, as you say in Magic: The Gathering, die to doom blade.
They might be good in a deck that’s absolutely full of huge low-to-mid-cost threats like this, where you’ve got twelve minions that demand hard removal, or dispel in the case of the vindicators and decimus. Testing is required.
