atmas´s is better at the end of the guild, after frozen and sunfire, but good work, like it =)

Great build,
Just tried it. i was tanky yet did alot of damage, i loved it!
Just got 12/3/9 with it (: didnt finish infiity tho, got to B.F. then they surrendered as we were pushing inhibitor turrets. (ranked) Also, great pusher, you take down turrets very fast, i even out dmged my teams Xin Zhao.

I think the early Atma's is a bad idea, get it after Frozen Mallet & Sunfire Cape, since the damage output on Atma's mostly comes from your HP, which means you won't get that much damage from it when getting it that early.

The items are pretty good except for the phantom dancer, it is a bit questionable, jarvan does not really scale with attack speed all that well. Perhaps swap it out for Banshee's Veil
