Hahah yup, I decided to use the Compendium talisman images to make it easier for people to look them up over there. Just gotta look for the right icon! Had thought about using the little in-game square buff-icons, but they don't always match up with the talisman images, and are harder to identify at a glance. Compendium ones are much better, and properly colour-coded.
This is the team I've been using, gets around 3-3.30min auto runs. It's mid-range at the most, but does use a few event-exclusive talismans/characters. Should still be a decent starting point to help people with their own team building. As long as you can deal with Perfect Immunity and Perfect Immortality, Insanity isn't anywhere near as annoying/difficult as I'd expected.
Have had 3 defeats in 100 runs though, in different places, but it seems that Green Onyx Son can rarely be killed during the first wave. One loss was to Cyborg Eddie though, which shouldn't be possible due to my Orbits, so who knows what's going on in there...
UPDATE: The Rider talismans in Waves 2&5 can inflict Perfect Sleep on your whole team. Had been wondering what was causing that. Something to be mindful of.
Flight of Icarus Eddie Lantern, Warlord, Cosmic My strongest Eddie, capable of dealing huge amounts of multi-hit damage when Warlord triggers. Can cleanse and remove damage shields. Any hard-hitting and durable Eddie should work here. The Killer Prime Persecution, Shell, Cosmic His permadeath passive helps deal with the Light talismans, and Bloodlust from his basic helps trigger my Warlords. He hits like a wet noodle beacuse I don't have any good talismans for him yet, but his job is to stay alive and debuff the enemy. 6* Warrior LoL Orbits Awakening his first level turns his basic attack into an AOE that removes Perfect Immunity, which a lot of enemies in here have. The Orbits help him cleanse your team and purge the enemy's buffs. The Orbits also mean the final Cyborg boss can't really damage you, as all he does is true damage. Sentinel Onyx Son Singularity Gives everyon an Accuracy Up buff (super good with LoL's Extra Turn change), removes enemy buffs, revives fallen allies, and with Singularities, he will continually steal the shields the boss Cyborg gains every turn.
