Haven’t tested Ninja. There’s another card that requires some pretty big workarounds, and I’m not comfortable testing it in a deck that’s already doing that for its own synergies. If Ninja were a Rogue, though, I definitely would be!

UM just isn’t flexible enough. It’s “reach,” but we have to already be getting through for it to work, and it makes us even weaker to spot removal. High risk, low reward.

As for Squad, it’s pretty easy to enable in this deck. I just don’t think there are a lot of decks that it’s great against. If Ad Nauseam or Valakut show up in droves and hassle this deck, I would try a Squad in the side. Just one is probably fine it costs 3 to prowl, giving us time to dig for it with Fortune and Serum.

Good MUs:
– any deck with important x/1s (Affinity, Elves, Infect, CoCo, Spirits)
– bad midrange decks (Mardu, UWx)

Medium MUs:
– highly competent midrange decks (BGx)
– go-wide aggro decks with x/2s (Merfolk)

Bad MUs:
– big mana with a clock (Tron, Eldrazi)
– linear spell-based combo (Ad Nauseam)

I’ve tried 1-4 Sprites and like two copies the best right now. They can be clunky in multiples, and this deck likes to play its cards on its own turn for the most part (Serum, Fortune, Brutality, creatures, etc.). Holding up two mana is often not a great plan until we start getting to three and four mana and also gain access to Snapcaster plays. But I still like having more than one copy of SSS in the deck since it’s great with Traverse (and Imposter), and we do want to draw it naturally in many scenarios.

Similar deal with Snapcaster: it’s a card we really need access to in the deck, but we don’t want to flood on them. I’ve also been happy with two of these.

Prowler tends to enable prowl reliably against decks without creatures, and provide value against ones with. Running eight+ one-drop Rogues also lets us include Cloak and Dagger, which makes them each perform better on their own.

I’ve found a one-mana creature with a sometimes-relevant upside to perform better than two-mana creatures with more reliable benefits, such as Looter-il-Kor and Obsessive Skinner. But for a long time we just didn’t have a one-mana Rogue available whose sometimes-relevant upside was relevant enough of the time to warrant its inclusion; our closest analog was Guul Draz Vampire (which I did try in some shells). Prowler is a huge upgrade.

If Delver were a Rogue, we would snap-include it. I mean, we likely wouldn’t have to, as Thieves’ Fortune might just find its way into Delver decks and sate the hunger that drives me to brew with Rogues in the first place. But without that card type, it’s way too much work to include Delver here. Keep in mind we also only run 20 I/S in this version, and my previous versions have played even fewer.

I have actually found the bar for one-drops to be playable in Modern to be quite low. The main requirement is that your deck does not struggle against Tron and other linear combo (and -esque) decks, which can be adjusted for via sideboarding; otherwise, one-mana 1/1s are just not going to get you there in those matchups. Beyond that, creatures that always trade for removal at parity or better, and synergize with your deck, are generally fine. More on this principle here: http://quietspeculation.com/whats-goyf-benchmark-creature-playability-modern/

Why not play the full set of Spellstutter Faeries? Or the playset of Snapcasters?

The 1/1 from AER is cute and while I apretiate (and respect) its applications (killing Dark Confidant is no joke), my question is: how often does it connect with the opponent’s face to enable prowl?

Is enabling prowl its only use? If so, what aren’t we playing peppersmoke in its place?
-1/-1 breaks a Goyf vs Goyf stalemate. Traverse for him or comboing it with Faerie Impostor gives a creature -2/-2 which is very relevant. All that said, its still a 1/1 for one for which we devote four slots in the deck; is he worth it?

I’d like to see a list including Delver of Secrets, Pestermite or Ninja of the Deep Hours (Oh god, I wish he was a Rogue). Did you already tested and dismissed those cards?

Anyway, keep up the good work!

English bad, me apologize.

That makes sense.

I tested Blossom for a couple days and didn’t like it. That card works better with more disruption (especially discard). I think it’s a little slow for this kind of deck, although I do like its applications with Cloak.
