Ok then my suggestion would be as follows:
Team:
Leader: Green Odin
Helper: Velk/Sorrows AO (Sorrows has higher RCV @ 804)
Sub: Blue Rip
Sub: Black Rip
Sub: Siren The Enchantress
Sub: Neptune
Difficulty - HIGH
Round 9 will either be impossible or easy using Odin...
Using that setup, you can survive the worst case Round 1 Scenario.
Gonna type up a strat for you now... will edit this post when I finish
Assuming you can survive ... and delay while all your skills get ready..
(read previous post about round 1 setups)
Round 2
You can blue ripper to almost kill the devils (they will have 6000hp left) and the knights will have 10,000hp left. Combined with Odin that leaves you with... 2 almost dead targets. Need to make a judgement call based on their timers as to which target you Odin.
Best case... 2 knights on different timers.
Worst case... Devil Knight
Odin to get 2 remaining, then repeat what you did on round 1 to refresh all skills.
Round 3
If you had a blue ripper... then all your skills have refreshed! Blue Ripper here AND Neptune... if you see a target that will live long... Odin him.
Round 4
Black Ripper to round 5!
Round 5
autoheal 1875 hp over over 5 turns... SNORE
Prepare the board to maximize your dmg and setup hearts using StE... (this will probably be dark, green or light depending on the levels of the Black Ripper / AO / Odin )
Round 6 and 7
If you see 5 devils... you die the first round they attack together.
If you see 4 devils... you have one extra round to survive.
Depending on how many knights attack on the same round you need different HP to survive..
Ideally you get your devil bad luck out of the way on round 6 and black ripper.
Which lets you Blue Ripper Strat round 7 and refresh all skills.
If Round 6 AND 7 are Devil heavy... nothing you can do but hope you can kill them off before you die... recharge before you get to round 8 once you get down to a manageable number of devils/knights ( you can survive 3 devils with one heart match for a couple turns...)
Round 8
Black Ripper
Round 9
If Alraune is on the same timer, you cant win using odin no matter what you do. If they are on different timer, easy autoheal to win.
Round 10
If you can get here, you can win with odin.
