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.

[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 Khalni Heart Expedition
[24 Lands]

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.
