True Damage Senna

It should be noted that this composition was played in the last patch, but it didn't have very good results. However, in this new patch is now one of the best comps for sure. In this composition, you have to play Slow Roll in level 6, until you hit the Senna 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 Senna, and your secondary carries will be other True Damage and Aphelios. As for tanks, the items will go in Ekko.

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 Akali as an off-tank, and the items that you may have left over from Ad can go in Aphelios or Qiyana. Additionally, it is important to emphasize that because of being a Reroll composition, any augment that gives you experience should never be take.

Senna best item is Giant Slayer, as she does ad and ap damage, and she benefits from both stats. The other item is more flexible, but the best is Jeweled Gauntlet. With Superfan she gains Spear of Shojin, but still, another Spear of Shojin, Guinsoo's Rageblade or Nashor's Tooth is not so bad. Tank items, whenever possible, go into Ekko before Neeko (except in situations of not getting ekko level 2). Akali 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, and Thief's Gloves since it is generally good.

The positioning of the Senna is not very relevant on which side it is placed. Even so, since Senna ultimate does damage in area, it is advisable to put your tanks together so that the rival units also get together.

To play this composition, you need Senna headliner +1 True Damage. 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 Superfan with the Senna headliner, and at level 5 you play Ekko for 4 True Damage or a Rapidfire. When you reach level 6, you will just play 4 True Damage, 3 Superfan and 2 Rapidfire, and Slowroll for Senna 3-star. If you find a lot of Aphelios units, you can play it 3-star, but It is not necessary.

When you find Senna 3-star, you will just level up until level 8. In this level, you will just play 6 True Damage.
