The goal was simple but its ambiguity made it more difficult than it sounds; make a build that's quite good at everything: AD, AP, AS, HP, MS, and sustain. However, crit has no place in this build as it requires a decent amount for the effect to be noticeable and none of them gives anything other than AD.

	Teemo is one of the few champions that can utilize pretty much every rune. Prototype: Omnistone enables Teemo to trade very often due to its low cooldown while providing sustain and utility each rune has to offer. You can quickly cycle between each rune for lots of pokes before going all-in when getting Press the Attack or Lethal Tempo. However, it may become a bit inconsistent in team fights so you must adapt your playstyle according to the current rune.
	Hextech Flashtraption opens up many play options such as jumping from bush to bush or to gank your own lane. The channeling time is longer than his passive, meaning that he will gain his attack speed buff after. (You need to be creative with one).
	Future's Market gives him an item advantage as it is crucial to get Berserker's Greaves asap in the early game, which gives Teemo more DPS than an AP item.
	Cosmic Insight's item haste decreases Blade of the Ruined King and Tear of the Goddess cooldown. Moreover, this gives spell hast so you can utilize Nimbus Cloak and Hextech Flashtraption even more often.
	Nimbus Cloak synergizes well with Hextech Flashtraption and Ignite, which allows Teemo to kite and chase the enemy. Pairing this with Cosmic Insight means that you can use them more often. This also provides Teemo with an extra bit of mobility since W alone isn't quite enough.
	Gathering Storm gives lategame scaling is way more beneficial compared to an earlygame runelike Scorch since this build is a hybrid. This means that having more AP is definitely better.

• At the start of the game, you can go invis in the lane before minions come in if your rune is Lethal Tempo, Hail of Blades, or Electrocute, you can start by going invis in the lane then play really aggressively once the enemy comes into the lane or even go all-in( Press the Attack can not be the first rune). However, this is not suggested if the enemy has a good level 1 such as Riven.
  
• Press the Attack, Hail of Blades, Lethal Tempo, and Phase Rush are runes that you can easily all-in the enemy with after poking them down to about half health with other runes.
  
• If the current rune is Predator and the enemy's HP isn't low, you can look for romes. Alternatively, you can recall if you have enough money(don't forget you have Future's Market) and use it to quickly get back to your lane. However, if none of these applies, just use it to and poke the enemy once to instantly cycle the rune.
  
• Dark Harvest increases the damage or attack speed of OTHER RUNES.
  
• Fleet Footwork on the enemy CHAMPION for more healing.

• Hextech Flashtraption can be channeled for up to 2.5 seconds, while Teemo's passive takes 1.5 seconds to activate. This means that after using Hextech Flashtraption, Teemo will gain attack speed, which will allow you to make the most use out of the duration wby getting close to the enemy. Without this rune, this part of Teemo's kit will be impossible to utilize in this kind of situation. You can use this after going into a bush or standing in your wave to engage. This is much more effective than standing still than running in. Furthermore, the Nimbus Cloak gives you a bit more speed after using Hextech Flashtraption. Combined with Teemo's W, you can outrun most champs.
  
• Nimbus Cloak's speed depends on the Summoner Spell's cooldown. This means that Hextech Flashtraption gives less speed than Flash. However, Hexflash gives Flash's speed for a fraction of a second for some reason before decreasing back. We can capitalize on this by spamming right-click while channeling Hexflash to start moving instantly after and gain a tiny bit more distance.
  
• Channeling Hextech Flashtraption will break your invis even in the bush so you can't use this to juke like in ss9. However, your stealth won't break after the flash if the destination is inside a bush. This means that this can be used in sevral places where there's a but on the opposite side of a wall such as from the blue side to the river's bush so the enemy can't spot you with their ward.
  
• You can use Hextech Flashtraption to gank your own lane from the jungle if the enemy is attacking your tower. This gives you the element of surprise, speed and attack speed.
  
• You can enter one bush, Hextech Flashtraption to another, and rush out to kill the enemy. They won't be expecting this coming.
  
• Remember, Ignite gives you lots of speed so you can use it as Ghost too.

	Nashor's Tooth is a pretty reliable early game item for Teemo as a lot of teemo's DPS depends on his auto attack. This item also gives a lot of attack speed and on-hit along with AP, which makes it a very solid first item
	Berserker's Greaves is better than Sorcerer's Shoes since this build deals mixed damage instead of AP. Instead, gaining attack speed is beneficial to both and allows you to proc Blade of the Ruined King even faster.
	Riftmaker gives Teemo sustain, a bit of tankiness, and TRUE DAMAGE which makes it very difficult for the enemy tank to build against. The mythic passive also gives more AP as not many AP items are built.
	Blade of the Ruined King gives Teemo more AD damage, chasing, kiting potential, and the ability to kill tanks. This percentage HP damage is also benifits Riftmaker and the healing from the two items combined makes it even harder to kill you.
	1.Stand still 2.Go invis 3.Appear with full HP (you also get AH)
	Seraph's Embrace is an essential since Teemo runs out of mana pretty quickly so you have to manage your ability well. This item allows you to use your abilities more often while providing a ton of AP too.

Overall, this build will give you: 145AD, 387AP(minimum), 35AH, 1.91AS(passive not included), 3162 HP, 6%max HP damage, 9% bonus true damage, 10% life steal, and 16% omnivamp. This build should be pretty good at everything, although doesn't excel at anything other than making the enemy's life miserable.
