Most viable deck post rotation.

[All-Mana Mania]

What so you think the most viable deck in standard when rotation comes?

[Hunteroffire9]

Rdw will be solid, and azorius control because we will have {sphinx's revalation}, {supreme vercidt}, {azorius charm}, {aetherling}, {angel of serinity} {jace architect of thought} and {jace memory adept} so azorius will be real good

[All-Mana Mania]

I think Orzhov would be good. Enchantment deck would be good. Naya midrange is where I'll be going with ajani domri rade, archangel of thune, etc.

[EvACiDe]

Borzhov I think will be huge. {R}{W}{B}

Totally forgot about that. It does seem it will be pretty good!!

[Agrus Kos, Enforcer of Truth]

RDW (or red/something aggro) is almost always a viable deck.

It's really hard to say without actually seeing any Theros spoilers coming in yet, and only seeing what's going out.

But based on what we can see, I think green-white will be strong (possibly a continuation of hexproof auras or just agro auras. Theros is supposed to be enchantment heavy, after all, which may potentially make up for the loss of Geist and Invis. Stalker)

I see some potential in Rakdos agro/midrange, which is what I am attempting to build for. If the format slows down just a half-step with Innistrad block gone, {Rakdos, Lord of Riots} could become much more popular.

{Obzedat, Ghost Counsil} and {ætherling} will be very difficult to remove. Ætherling for obvious reasons, but Obzedat is immune to the now-best removal spell in standard ({doom blade}) and can't be removed by any sorceries. I predict Obzedat coming in for more play and a price tag rise to match.

There are a lot of hydras around, and more coming in Theros. A green-red Hydra deck with ramp and Ruric-Thar is possible as well.

But like I said, it's hard to guess without knowing exactly what Theros is bringing. But those are some hypotheses I'm making.

Mono-red has the potential to win by turn 3-4. And that is just RTR block constructed. Imagine what Theros might offer to that.

I'm hoping for lightning bolt...it only makes sense...maybe it's wishful thinking but still.

Apparently wizards said if lightning bolt got reprinted they would fire the people that did it..

Well what if they don't call it lightning bolt. It could be something along the lines "Lightning Strike". No one would ever know!

That would be even worse because modern decks would run 4 of each....

[rarehuntertay]

I could see a reprint of  {Hammer of Bogardan}

[Bozo_Law]

UB/Esper Control will rule the roost! I hope...

[JustAWalrus]

Dega auras with {Fencing ace} {Dark Favor} and {Madcap skills} Thats what I run
