Detailed strats, please? =)
Ok, first here is my team.
Dark Metatron - max lvl and awakenings
Hanzo - max lvl and awakenings
Fire/Dark Ares - max lvl and awakenings, +42
Witch of the Night, Lilith - lvl 57, max skill, 1 awakening (for auto heal)
Witch of the Night, Lilith - lvl 52, max skill, 1 awakening (for auto heal)
Dark Metatron friend - max lvl and awakenings, +297
Total team hp must be at least 13,335 to survive the preemptive dub mythlit attacks on the 3rd stage.
Stage 1. You need one 5 dark orb match (a row is not necessary) and 2 or 3 off color matches to easily clear the little lits and leave the mythlits. My team has 6 skill boosts so if i had my Hanzo skilled up to 6 turns I could use him right away. My Hanzo is still at 9 turns so I depend on some luck here. If there aren't 5 dark orbs, try to combo as much as possible with dark, fire, and light orbs to kill at least 2 of the little lits. You can survive 2 hits from the little lits and hopefully the mythlits will try to bind instead of attacking. Once you clear the little lits, kill one mythlit at a time. If you are below 80% health, one light orb match will kill 1 mythlit (your leaders can't be bound if fully awakened). Do not match dark orbs unless you are above 80% health or you will kill all the mythlits. Stall until Ares is 5 turns away from having his skill charged and 1 Lilith is 1 turn away from having bind expire (the other Lilith should be 3 turns or less from having bind expire). Heal when possible. Once all the binds are almost gone, kill the last mythlit and keep healing while eliminating light and green orbs.
Stage 2. Use the first Lilith right before the dublits attack. Make sure you heal to full health and keep eliminating light and green orbs.
Stage 3. Use the 2nd Lilith right before the Tamadra binds and keep eliminating light and green orbs.
Stage 4. On the first turn, just eliminate as many light and green orbs as possible. On the second turn, take the hit to get in the <80% hp zone. Use your skills in this order: Ares, Hanzo, Dtron and you will have close to a full enhanced dark board. Now make 2 big horizontal rows of dark orbs using the poison orbs to separate the rows, this should 1 hit ko both Twinlits. If there are still light and green orbs on the screen make sure they do not keep you from making full horizontal dark rows. You can't survive matching 6 poison orbs at once so stagger them matching 4 and then 2. Example below where x are poison orbs.

On 1 run, the Angelit attacked first putting me under 80% hp but the Devilit did not attack yet so there were no poison orbs. The board was almost all dark so there was no need to make rows and I killed both Twinlits easily.
edit. you can use Haku instead of Ares and not worry about poison orbs, but her skill does not make the 3 colors evenly so you could end up with a lot of blue orbs and not have enough dark orbs after using Hanzo to 1 hit ko the dark Twinlit.
