I am not a in depth person, so any questions that you have, feel free to send me a question, and I can help fix it.

My runes are standard for all of my attack power dps. ex; Corki, Tryndamere, Riven, etc.. Combined, they make you a durable start, and tih the addition of the items, it can make you quite a force to be reckoned with.

Greater Mark of Attack Speed- It is useful because it allows you to focus on damage before having to increase you speed. combined with the slowing effect of Phage or Frozen Mallet they can be very helpful

Greater Seal of Armor- Is good rune choice because it provides you with flatout defense against melee and ranged attack daamage people. ex Corki, Shaco, Xin Zhao

Greater Seal of Defense- Is a good rune choice for the per level addition to your srmor. Making you even more durable as you level up more.

Greater Glyph of Magic Resist- These runes will help you be more protected from those pesky casters that seem to think they will hurt you. it gives you flatout magic resistance against the ability power users. ex Brand, Morgana, Lux

Greater Glyph of Scaling Magic Resist- these will further your durability against magic users as you both procede to level up and get stronger.

These masteries are ones I use for every champion I play. which is why I have the increase in ability power Archmage's Savvy and Burning Embers . and the increase in attack damage Brute Force Lethality . You do not have to use this set of masteries if you do not like something about them.

Doran's Blade is a good starting item for the increase in health and the small attack damage boost. it makes you a better pregaming champion.

You can go with Boots and Health Potion if you want, but you will be a bit more weak and squishy.

After a doran item, I go for the beserker greaves, for the increase in attack speed, and obviously the high movement speed increase.

I grab a Vampiric Scepter because I tend to get aimed at when I am playing, so I take the time to grab some minions for the gold and to regain some health for I engage in another fight.

I focus on building a Phage next, grabbing the longsword first to increase my damage on champions and minions. after the Phage, I get a Giant's Belt for the increase in health and to build it into the Frozen Mallet

next are the Dagger to increase my attacking speed and make getting kills easier by combing the speed with the slowing effect of the mallet. After the Dagger I get a [brawler's gloves]] for the crit strike and to build into the next item

I get Zeal after the gloves, this will be build up futher into a Phantom Dancer
With the increase in attack speed, movement speed, and nice boost to critical chance, Phantom Dancer is the next item.

Now, with the speed and slow you have on, you need to build up some damage on him. So I grab a B.F. sword. The massive boost from this item will make you much more of a threat while you fight.

Upgrading your Vampiric Scepter and B.F. sword a Bloodthirster is the next choice. Once you get this item buffed, you will be hitting hard, and fairly fast, combined with your slow effect, you should be able to get kills on your own quite nicely.

To make yourself even stronger, i suggest buying a Infinity Edge next. The large damage, crit chance, and passive of it will make you a power house now.

selling your Doran's Blade to buy a b.f. sword, you save up and buy a Black Cleaver. The increase in attack speed, and boost in attack damage makes you able to take down any champion that opposes you.

He isn't the greatest support champion, he prefers to kill everyone.

Once you finish the build, team fights should be a breeze for you.
join/start it with a Nimbus Strike after it hits, and you melee once more, immediatley activate your Crushing Blow. Any team member that was low on health should have been able to escape by now. If the are still being chased by some one you missed, you need to react to them. Using Flash and either Nimbus Strike or Cyclone, the slow will be applied from the Frozen Mallet and they should be able to escape and heal.

if it is you trying to escape, try to Nimbus Strike to an enemy who is away from the fight, minion, champion, or monster. if they still insist on chasing you, keep running and when the nearest brush comes close, use your Warrior Trickster. now, there are three options to this.
1. You can run into the bush, use Warrior Trickster and hope they stop to attack it while you run away
2. You can use Warrior Trickster and run into the bush and continue running
3. This option is best for when you only have one or two people chasing you. Use Warrior Trickster and immediatly run the way they are coming from and use Nimbus Strike onto anything you can, and use your Flash either over a wall, or even further the way they were coming from.and just keep on running away, try to escape towards an ally who can hold them off while you escape.

In any team fight Cyclone is the best option. Join in using Nimbus Strike then Crushing Blow and activate Cyclone. the damage output should be quite high and able to do a large amount of their health. finish them off with basic attacks,which applies the slow, almost sealing their fate
