This is my first build, just trying to figure this out.

Updated 1-8-11 - item build a bit with an explanation.
Updated 1-14-11 - still figuring all of the features out, split into chapters. I only work on this at work, cause when I'm home....It's game time!

I will try to go over a few things.
- Pro's & Cons
- Skills
- Summoner spells
- Gameplay
- Items

Pros
-Very quick and large damage output.
-Ultimate abilty reveals stealthed champions.
-Has a great stun ability.
-Ultimate ability also allows you to get ANYWHERE on the map almost instantly.

Cons
-Squishy
-no real escape mechanic besides your yellow card
-makes your team angry at times if you ULT into their lane to help and "steal" their kills

WILD CARDS
Throws three cards which deal 60 / 110 / 160 / 210 / 260 (+65% of ability power) magic damage to each enemy unit they pass through.

Cooldown 5 seconds | Cost 60 / 70 / 80 / 90 / 100 mana | Range 10000

Lackluster move and it wastes so much mana that I recommend not getting it before level 6.

PICK A CARD
Cast once to shuffle the deck and again to choose your card, enhancing your next attack.

Blue Card deals 30 / 45 / 60 / 75 / 90 (+40% of ability power) bonus damage and restores the bonus damage in mana to Twisted Fate.

Red Card deals 30 / 45 / 60 / 75 / 90 (+40% of ability power) bonus damage plus his attack damage to units around the target and slows their movement speed by 30 / 35 / 40 / 45 / 50%.

Gold Card deals half the bonus damage of Red and Blue Cards (+40% of ability power) and stuns for 1 / 1.25 / 1.5 / 1.75 / 2 seconds.

Cooldown 5 seconds | Cost 40 / 55 / 70 / 85 / 100 mana | Range 200

This is one of the most important moves for TF since the Red card does AOE damage and the Gold card stuns them and the Blue card gives you mana back so it keeps you in your lane a little longer without having to go back to base as often.

STACKED DECK
Passive: Every 4 attacks, Twisted Fate deals an additional 55 / 80 / 105 / 130 / 155 (+40% of ability power) damage.

In addition, his attack speed is increased by 3 / 6 / 9 / 12 / 15% and his cooldowns are decreased by 3 / 6 / 9 / 12 / 15%.

This move is your bread and butter, just throw a couple cards at minions until it is ready (you'll see the cards floating around you when it's gonna be the next card). Try to use this card to hit champions with for harrasment if they are near the minions.

DESTINY
Reveals all enemy champions (including stealthed champions) for 6 / 6 / 6 seconds.

While Destiny is active, Twisted Fate can teleport anywhere on the map.

Cooldown 130 / 110 / 90 seconds | Cost 150 / 125 / 100 mana | Range 25000

This is why you get extra gold, it allows you to kill wounded people and even stealthy wounded people. Another good thing about it is that you can use it if the enemys have been missing for a certain time you could use it too see where they are at.
Also, don't forget about your ability to take down towers quickly. You can ULT into the enemies base and quickly take out inhibitors that have respawned or take out the last tower or two if your minions are there already....gotta love the ability to backdoor win while the enemy team is pushing your base, similar to Pantheon's ability.

I personally love ghost and exhaust with TF. Even after the patch....I loved blind more though :)

You can replace ghost for flash or ignite if you really want to, but I find ghost to be the most useful overall...but choose whatever helps you the most with your playstyle.

I would never replace Exhaust though, it has saved my *** all too many times and leaves the champ that got slowed QQ'ing for a while most of the time. And it can usually buy you the time to get another yellow card in their face, that should buy you the time to either GTFO! or finish them off!

Be careful early in the game. You will be able to deal good damage, but you are also very squishy....do not forget this! Once you are lvl 9 and have 5 points in stacked deck, every forth attack hurts pretty badly.

This is where you need to make a choice as to how the game is going. If your getting some kills already, you should probably get you Sword of the Divine when you can, even before boots if the game is shaping up that way.....BUT, if things aren't going your way, may have died a couple times, or just not getting any or many kills and you end up being on the short end of gold. While people are moving into thier mid game and your just not quite there, skip Sword of the Divine and go straight into your Zeal and then Bloodthirster. You can get SotD later if you feel the need...it's passive later is so so, but the active helps against tanks and heavy dodgers...JAX!

Also if you feel that Bloodthirster is not for you, then I would at least grab an Executioners Calling for some cheapened life steal and crit.

Don't be afraid to get the cheaper items first to get ahead a bit, then once you get a better grip on the flow of your paticular game, then you can dip into the more expensive items.

Make sure your using your ult to see where enemy activity is. Especially when your facing stealthed champs! A well timed ult to reveal a gank on a teammate that ends up saving thier life will never go unappreciated. And always always always teleport somewhere when you use your ult, That way the enemy team not only knows that you know where they are, but they don't have a clue where you went....until your raping them or their turrets!

I always start out with ATK SPD dagger and a health pot. Then once you've built up enough gold for you boots, GO GET THEM! unless you've been lucky enough to score enough kills to get SotD (as explained in the Gameplay chapter). Otherwise go ahead with boots first and then get your sword. Once you have these two items grab a zeal once you have the gold, it's a nice boost to your crits, ATK SPD, and of course movement speed. Once your this far, depending on how mid game - late game is shaping up, try to get the BF sword before the Vampiric Scpeter. But if that isn't looking to work well and you need a little help sooner than later, grab the Life Steal first and then go back for the BF sword. And of course, upgrade that into the Bloodthirster ASAP and get that sucker charged up!

You can change the last couple items in the build to cater to your needs depending on what the other team has in store for you. I never have a need to change the initial four items though. I have on rare occasions, upgraded the Zeal into the Phantom Dancer but never before getting Ifinity Edge. But usually when the game is lop sided and I happened to be back at the base with the gold to get it all at once with no need to get creative with the build. The game is usually almost over at this point anyways.

I hope any of you who try this build enjoy it as much as I do. GL & HF.

I'll continue working on this when I get the time, please feel free to comment and/or rate this. Looking forward to seeing what others have to say.
