The rules are simple:
Atleast 2 of your agents shouldnt be currently meta (or atleast strong enough for that map in the current meta).
And you should have some explanation of how the composition would operate
Edit: This is my comp idea for haven
Yoru, Veto, Harbor, Omen and Sova
The off meta picks:Harbor and Veto
The idea:
Attack side you use your omen to smoke deep initially... And the harbor cove to give your yoru cover. And also to hide what the yoru is doing from the enemy's view (like you can default this every round and then tp then fake and the enemy will believe its real)
Sova is sova for the yoru, omen is omen, and yoru we know
Defense side is when veto really shines. Attack side he's mostly playing back with harbor/omen for retakes. But defense you setup 1 veto tp to give you an out, and the other tp as a rotate in tp. Interceptor at the location opposite to you(depends on what position and how rigorous their clearing is) and your trap guards your back or your tp position (depends)
Harbor is stall, omen does omen, yoru is the rotator and aggressor with omen. Sova does sova
