Based on what's been spoiled in Zendikar so far, blue is going to bite balls.

Here's a concept deck you may enjoy playing just to make some blue mage's day absofuckinglutely miserable.

Fuck You Blue [A Standard Deck Concept]

[16 Creatures]

4 x River Boa
4 x Great Sable Stag
4 x Spellbreaker Behemoth
4 x Terra Stomper

[8 Instants]

4 x Lightning Bolt
4 x Volcanic Fallout

[8 Sorceries]

4 x Rampant Growth
4 x Banefire

[4 Enchantments]

4 x Khalni Heart Expedition

[24 Lands]

4 x Rootbound Crag
4 x Kazandu Refuge
2 x Gargoyle Castle
9 x Forest
5 x Mountain


Why this sucks for blue:

* 20 uncounterable spells (12 creatures, 4 instants and 4 sorceries)
* 8 end of turn burn spells
* 4 low mana, islandwalking, regenerating creatures
* Plently of mana acceleration to outrace counterspells
* Uncounterable flyer in the form of Gargoyle Castle.

Dear blue, it sucks to be you.
