This comp looks to reroll for 3 star units with the Redeemed trait. The comp revolves around Varus as the main carry. This comp can slow roll at level 5 for things like Leona and Aatrox, but ideally you will want to look for Varus 3 by slow rolling at level 6.
Go for this comp if you have a good start with Redeemed units and mainly attack damage items.
Level up to 4 early if you want to start a win streak. Level up to 5 to try and continue the streak. If you level up early, you won't be able to slow roll for Leona and Aatrox easily, so wait for level 6 to slow roll.
If you're weak in the early game, you can opt to save gold and lose streak instead.
You can choose to slow roll at level 5 for Leona and Aatrox, but this is only recommended if you already have a lot of copies of them.
Level up to 6 at Round 2 and put together the strongest board you can. Begin slow rolling for Varus 3 once you reach 50 gold. You can also look for Syndra 3 during this time as well.
Once you hit enough 3 star units, you can then look to hit level 7 and 8 to complete the team comp.
The Redeemed units make for a very easy early game board with 3 units. You can pair this with a Ranger alongside Varus, or a Legionnaire if you haven't found Varus yet.
At level 6, you can look to put in 6 Redeemed if you are able to find a Rell or a Vel'Koz. If you can't find one, you should simply run the 5 Redeemed units alongside a Ranger like Ashe or Vayne.
Redeemed units spread the trait buff to others once they die, so you really want to ensure that Varus is the last unit that stays alive. This will give him a lot of bonus stats which will make him deceptively strong at the end of the fight.
