Dubbed “some weird Glittering Wish control deck” by my first opponent at a GP Trial last week, this is my likely choice for the remaining PTQs and GP of the current block constructed season. It plays out as a mid-range aggro/control build with a heavier emphasis on control. Obviously, it’s chock full of removal, and it can Wish its way into additional solutions or finishers as needed. I still need to watch the Sliver interactions more carefully, as I missed several opportunities to eke more utility out of Slivers at the Trial (and that was before I put in the Darkhearts).
I’m still considering the contents of the non-Wishable portion of the sideboard, and I’ve had someone on the forums lobbying me to stick Haunting Hymn back into the main.
BRG control

27 Spells:
Harmonize
Edge of Autumn
Coalition Relic
Damnation
Void
Tendrils of Corruption
Disintegrate
Slaughter Pact
8 Creatures:
Sprout Swarm
Akroma, Angel of Fury
Stormbind
Stronghold Overseer
Magus of the Library
25 Land:
Urza’s Factory
Urborg, Tomb of Yawgmoth
Graven Cairns
Grove of the Burnwillows
Terramorphic Expanse
Pendelhaven
Forest
Swamp
Mountain

Completely untested (notice the lack of sideboard, as will be true of many of the decks from this point on). This build packs the usual mess of removal, along with Harmonize to refill your hand to the point where the Magi can keep topping you off on cards. I suspect this build wouldn’t do that well, but I wanted to see what I could do across the three colors.
Goblinstorm

32 Spells:
Lotus Bloom
Psychotic Episode
Mindstab
Imp’s Mischief
Slaughter Pact
Empty the Warrens
Emblem of the Warmind
Haze of Rage
4 Creatures:
Rift Elemental
24 Land:
Dryad Arbor
Graven Cairns
Swamp
Urborg, Tomb of Yawgmoth
Mountain

Although Dragonstorm never really worked in block, and Ignite Memories is awfully conditional, I’ve always thought a Goblinstorm deck should be able to work — if it can manage the kill in its storm turn. This is one take on the idea, built in response to someone’s request for assistance with block Goblinstorm decks. This one tries to pack removal and disruption to live long enough to see the storm turn. A different, possibly more effective, approach would use a lot of digging and filtering, with cards like Foresee setting up the storm turn. Still, if this deck can go off at all properly, it can do an egregious amount of damage in a single turn thanks to Haze of Rage and Goblinstorm.
Swath of Rage

8 Creatures:
Greater Gargadon
Mogg War Marshal
28 Spells:
Rift Bolt
Empty the Warrens
Emblem of the Warmind
Lotus Bloom
Haze of Rage
Grapeshot
Pyromancer’s Swath
24 Land:
Dryad Arbor
Fungal Reaches
Keldon Megaliths
Zoetic Cavern
12× Mountain

This build combines multiple storm cards and Pyromancer’s Swath to try and make a more resilient storm deck, with multiple win conditions. In addition, it loads in Mogg War Marshal (and friends) as Emblem targets, and the Gargadon as anti-Tendrils and yet another win condition. I’m looking forward to testing this quirky variant.
The Dryad Arbors in both storm builds are there to give uncounterable Emblem targets, by the way. Drop the Dryad, play the Emblem on it, then go off with hasty goblins (and their friend, the hasty Dryad).
Xeno

30 Spells:
Damnation
Void
Tendrils of Corruption
Slaughter Pact
Reiterate
Curse of the Cabal
Bitter Ordeal
Disintegrate
Coalition Relic
4 Creatures:
Tombstalker
Bogardan Hellkite
26 Land:
Urza’s Factory
Kher Keep
Graven Cairns
Molten Slagheap
Urborg, Tomb of Yawgmoth
Terramorphic Expanse
Mountain
Swamp

This is an attempt to use Curse of the Cabal and Reiterate as control spells. It packs the usual B/R removal suite, and a quartet of solid finishers across those two colors, and then a 4:4 set of Curse:Reiterate. Very theoretically, the idea is that in the appropriate match-up, you’ll suspend a Curse turn four, then either they hemorrhage out trying to keep it from being played, or they let it play and try to counter, at which point you can Reiterate it (or Reiterate the counter targeting the counter, that works too), or they just let it go, in which case you Reiterate the curse and they lose three-fourths of their field. Follow that up with a Bitter Ordeal and you should be gold.
Again, I have no idea if this will work, but I’d like to try it. Curse has been awfully dead space in some decks I’ve tried in the past, but something just appeals to me about either hacking away half my opponent’s permanents or slowly gaining field advantage on them as they stall the Curse.
Unless, you know, they just Riftsweeper it.
