My build is about tanking early and destroying late but still being tanky late. if you can solo top that would be great because you will be very hard to kill early in the laining stages and when your jungler ganks you can easily get in the battle with his desicive stike and then spin.

These runes are pro runes because you wiil dish out damage and stay in lane by being able to take harasment. The marks will help for doing more damage early giving you about 9 more attack damage early. The seals will help you take ad harasment giving you a little over 12 defense. The glyphs will help with ap caracters giving you about an extra 6 magic resitence.
The health regeneration runes combined with his passive will make you an ultimate laning champion. The quintessences will help you with his large cooldowns so you can dish out more damage quicker.

The items i have you can mess with a little to your prefference. starting with boots for me is really helpful because you can get away and catch up to people faster. Another suggestion is to start with dorans shield so you have extreme health regeneration. i then finish off my boots with berserkers greaves for some attack speed so you can still do damage after you've cast all your abilites. You could also go for nija tabi or mercurys treds depending on who your laning against. I go straight for atma's after because of the armor and critical chance. After than build your big health giving items such as frozen mallet and warmog's for the extra damage that atma's gives you and the 1680 health to. Then get a bloodthirster just to sustain longer and all the attack damage. When you get this far you will want the attack speed, move speed, and critcical chance from phantom dancer.

I max jugment first because no one wants to stand next to and attack while you are spinning and its great for farming. Desisive strike next because then you have a strong silence early the a huge smash late. courage is always nice with its passive but you dont raelly need to actually use it frequently because you are already so tanky. Garens ultimate is amazing because of its base damage and its extra damage for the amount of health they have missing.

The summoners i use are flash and exhaust because flash is amazing for going towards champions and escaping same for exhaust you can slow them for a lot so your team can get away or destroy the target. This build works for me so if it dosent for you i will be suprised.
