I’m the anonymous commenter from above. I don’t race those decks, my deck is midrange. With KCommand and plenty of removal decks like affinity, zoo and burn are easy matchups. It’s hard for me to see an aggro deck with soulflayer race any other established deck because of the balance between maxing out on your Flayer keywords and not pulling too many dead cards in hand. I like the deck but playing with Reaver and ramp takes away from the burn strategy which in a competitive match would lose to more concentrated aggro IMO.

As the other poster said, Flamespeaker is a little less glass-cannony than Reaver, but I also think you want to be more all-in with a strategy like this. I don’t believe a double-striking Flayer alone is going to race Affinity, Burn, Zoo, Merfolk, and the other aggro decks. But a double-striker with lifelink? That’s going to be really hard to beat.

You can go more aggressive with Hellspark Elemental, and there might be some synergy with Flamewake Phoenix. Hell’s Thunder is another option in the haste department. Of these, Hellspark is probably the best, doing a Vengevine imitation while still improving Soulflayer and probably being more aggressive overall.

I play a midrange brew with a 2of of Soulflayer. I have a playset of Prophetic Flamespeaker. He’s got double-strike and trample, two very relevant keywords plus card advantage when he hits.

I agree with Rich – I think that Gravecrawler needs to be in here, so that Vengevine can function as intended. I like the deck’s concept overall apart from that, though – Dredgevine has been in the need of innovations in order to sit at the big kids’ table, and something like a beefy Soulflayer as an alternate win-con might push it over the top. I admit to being a bit leery of Drogskol Reaver as a 4-of, though – I know we want it for Soulflayer and as Faithless Looting/Lotleth Troll bait, but I’m still a bit apprehensive of it just getting stuck in our hands. Is Viashino Slaughtermaster really the only way to get Double Strike for the Soulflayer in Jund colors?
