I agree. That’s why I’m most anxious about Theros duals 🙂 They’re confirmed to exist, and I assume they aren’t super bad like the Kamigawa ones.

Since Thoughtseize just got revealed, every black deck just got a bit more viable. Thoughtseize + Lifebane Zombie seem pretty strong.

Wow. It seems like you have really been working hard to get a head start on the new format. That list seems extensive. I really like the idea of Kalonian Tusker in the GR Domri deck. Going with a base green seems like it could be solid. My worry with the other decks though is the mana. It’s hard for me to imagine they are consistent enough with just the Rav Block duals.

4 Elvish Mystic, 4 Experiment One

2 Gyre Sage, 2 Scavenging Ooze, 3 Kalonian Tusker, 3 Mizzium Mortars

4 Domri Rade, 4 Dreg Mangler

3 Exava, 3 Corpsejack Menace

4 Kalonian Hydra

24 Lands

Esper / American control will remain strong it seems. I have no idea why the list in the article doesn’t play Jace, I found him to be crucial in all of my builds. Although we should note that the control decks do lose quite some power with the rotation of Augur of Bolas, Snapcaster Mage and Restoration Angel. New cards like Blood Baron, Boros Reckoner and Izzet Staticaster do a reasonable job but there’s an obvious difference in power.

RDW will still be playable in Standard, but since you are including Mutavault (hence 2-3 more lands than block) and maybe some Burning Earth, it will probably become slightly bulkier, maybe going up to four with Chandra, Pyromaster. The Selesnya deck will also remain a strong contender.

Here are the other decks I’ve been playtesting, aside from the ones already mentioned:

RBW Midrange: Dreadbore, Boros Reckoner, Blood Baron, Aurelia, Rakdos’s Return

(viability will depend on Theros duals)

Naya Hexproof: Gladecover Scout, Ethereal Armor, Madcap Skills, Unflinching Courage, Boros Charm (depends on new hexproof creatures and auras)

Grixis Control – control variant with more disruption

GWB Midrange: Elf, Voice, Scavenging Ooze, Trostani, Archangel of Thune, Obzedat. This deck exists to beat aggro.

Naya Aggro: my pet deck, boasting the Ghor-Clan + Boros Charm combo. Experiment One, Voice, Domri, Reckoner.

White Weenie: the usual stuff + Mutavault, Banisher Priest, Ajani, Gideon and Brave the Elements.

Big Selesnya: going one step above Selesnya tokens. Everything from Elvish Mystic and Gyre Sage to Garruk, Caller of Beasts and Angel of Serenity.
