First off, learn to English. Secondly, I'd say you need at least some magic pen runes to help keep your shield (not armor) up. Also, mace of spades doesn't do all that much damage. Even if you want to go with it first, at least put one point in creeping death. Why berserker's greaves? Morde isn't really a great physical damage champion. If you're going to get warmog's, I'd probably get it earlier.
