I would recommend Yorick. He is quite tanky and casting his minions is pretty easy and they even follow the enemy around beating on them. Bonus!
He's also very powerful both bottom lane and decently good top. His mana problems aren't a problem in Dominion and his Revenge Ult ability is satisfying, or in a teamfight he can clone the nastiest AD champ.
Build-wise, I recommend 2 AD, 21 defense (movespeed&CDR), 7 utility (good hands and movespeed), AD/lvl reds, armor yellow, MR/lvl blue, AD quints. Though anything works to be honest...I just prefer the MS and decent CDR.
I'd start with a Pros Blade and boots, for both top and bottom.
I recommend Ionic Boots and a Brutalizer for his first few upgrades which give him massive CDR reduction and good spamming ability.
From here you can figure it out. I get Negatron for MR, TriForce for general buffage, and Odins Veil for more defense.
Another fine, more defensive approach might be:
Pros blade, ionic boots
(then in whatever order....)
-> Frozen Heart
Phage -> Frozen Mallet
Negatron -> Odins Veil
Hexdrinker -> Maw
