I think Nautilus is the best tank, or at least one of them. He has a knock airborne, shield, pull, slow, damage farming, health and stun.
Try to harass him to stop his farm.
How the Hell did I never think of that as a way to gain the advantage.
I LOVE MORDEKAISER
@ doomonkey's malz build: I don't see why you need to be that beefy when malz has such good range. Only his ult puts him in danger, but you have no CDR so you're not gonna be using it much anyway no matter how suicidal you are with it. Rod and rylai's and banshees and will of the ancients? All that defense and not a lick of CDR even on the runes; that's a damn shame on Malz if you ask me.This is my Malz which is rune- and mastery-neutral, except assuming -5% CDR to hit the cap. If you're serious enough about him to buy champion-specific runes (which I'm not), you can probably get by on all the pen marks you had and trade the void for something? And you can trade the mana runes for CD with the mana regen on tome + staff, I bet, or just make sure to get the -CDR in the offense mastery tree. Anyway, a starting place for you to think about.
