I got to go full commando with a team exactly one time. I was the solo guy matched with a 4-man premade, and they told me the plan. I think, if memory serves, we somehow won. Either way, it was a blast. 10/10 experience, would do again.

Everyone hits their stuff, enemy Team is gone.
Good players no trolls no feeders no excuses"having bad game" just good players doing well while the enemy is trolls. basically reversed rolls for once
If there is any adc you don't want to mix with Pyke, it's Jhin. Or vice versa.
They are both executioners, so their kits are in direct conflict, and Jhin doesn't get attack speed what with his 4 shot reload thing, so he can't take advantage of an enemy being pulled the way other adc's can.
Anyhow if you hadn't said ranked I'd do a thematic comp of some kind, but in ranked....
Adc Kalista, support Yummi (not the oathsworn), top Kench, jungle whoever, and mid TF.
Yummi attaches to Kench, Kalista absorbs the jungler, Kalista hops inside Kench ult, Kench brings all 4 people to wherever, and TF uses his ult to come too. 5 Man teleport.
Also works with Kench jungle and Shen top, but then Kalista can't oathswear the jungler since it's Kench.
