Does anyone see any deck types in Standard that will gain popularity during Gatecrash? Even unknown, new ones? I already am thinking about an Unblockable Cipher build, and an Extort Lifegain Control deck. I tend to think of things that never actually happen to be popular, but who knows?
With the new dual lands and some more control cards, esper/4c walkers.
How about a deck archetype were the premis is around searching for creatures. That bio visionary I'm kinda excited about using
Visionary clone and {primal surge} is likely but not super competitive.
Crypt Ghast will create a new high end beat down and/or reanimator. As well as a darker version of {omniscience}.
Defenders may be more prevalent as they gain more options.
Blue black control will be a top deck once more.
{Cavern of souls} will spike since their are great cards scattered over different colors.
Red green beat down is back with a vengance.
