This comp revolves around 3 starring Riven and possible Nunu as the main carries of the team comp. Abomination items are not required, but extra items can always go on Brand and Kalista for Sion.
Go for this comp if you have good Riven or Nunu items. Having a good amount of copies will also help 3 starring them.
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're weak in the early game, you can opt to save gold and lose streak instead.
At Round 2, level up to 6 regardless of your start. Put together the strongest team you can.
At Round 1, level up to 7. Roll a bit to stabilize your comp if you are weak.
At this point, you can choose to slow roll for a 3-star upgrade, or level up to 8 for a consistent power upgrade. You can also look for your 3 star units at level 8, but it will be expensive.
Having an early Nunu will help, but you can always just use Brawlers with Kalista as a solid start.
By the mid game, you want to have some copies of your 3-cost units to build around. This also allows you to put your items on early without needing a transition unit.
We prefer putting 3 items on Nunu instead of going for multiple items on the Abomination units. All of the Nunu items will be strong on the Abomination, and you can always put extra late game items on Kalista, Brand, or Fiddlesticks.
