Introduction
This composition has started to be played this last patch, and it gives very good results. In this composition, you have to play Slow Roll in level 6, until you hit the Jax 3-star. This composition is played with a tactic called Slow Roll, which mean that you will stop in some levels to roll above 50 gold, to find some 3-star units. Your main carry will be Jax, and your secondary carries will be other EDM units and Poppy. As for tanks, the items will go in Zac.
Augments
The best augments are Cybernetic and Combat Augments. Also, Economy Augments are very nice as you will need a lot of gold to roll down for 3-star units (you should never have 3 augments of this type, one or maybe two are fine, but no more). Furthermore, the augments that give you items are not bad because you will have Zed and Poppy as an off-tank, and the items that you may have left over from Ad and Ap can go in Zed or Lux. Additionally, it is important to emphasize that because of being a Reroll composition, any augment that gives you experience should never be take (except March of Progress).
Best Augments
Items
Jax best items are Edge of Night, Jeweled Gauntlet and a healing item like Hand Of Justice or Bloodthirster. Tank items, whenever possible, go into Zac before Sett or Amumu (except in situations of not getting Zac level 2). Zed will be the off-tank holder, with two healing items like Hand of Justice or Bloodthirster and Edge of Night (Sterak's Gage or Titan's Resolve are not so bad). Other interesting items would be the Sunfire Cape since it is very good in early and reducing the healing of the enemies is very relevant, Thief's Gloves since it is generally good, and Ionic Spark or Statikk Shiv since reducing Magic Resistance is very good.

Early-Mid Game
To play this composition, you need Jax headliner +1 EDM (+1 Mosher is not so bad). If you can't find it level 4 and 5 is not so bad, but it is essential to have it at level 6. So, at level 4 you play other Mosher units with the Jax headliner, and at level 5 you play Lux. When you reach level 6, you will just play a Bruiser, and Slowroll for Jax 3-star. If you find a lot of Lux units, you can play it 3-star, but It is not necessary.

Late Game
When you find Jax 3-star, you will just level up until level 8. In this level, you will just play 5 EDM, 4 Mosher and Amumu. In case you have Jax headliner +1 Mosher, you will play 4 EDM and 6 Mosher instead.
