S&M redux (you may never have the ability to build this team, but if you can here it is.)
Mono purple banner,
Sun & moon (sorcerer***) magic bonus
Avina
Giant spider***
dokkalfar***
Info
Avina 2 casts to get max souls.
Sun & moon buffs magic of everyone who is not maxed out, aka the two summoners
(reason i want dokkalfar damage to scale off of magic even for split damage)
Giant spider can with one spell fill the entire team some days or just fill sun and moon other days.
Avina is a counter to undead troops and normally (where i am at) 1 shot undead troops.
This team has more staying power than most other teams. Winning can come down to reconstructing the team into a spider brawl. Dokkalfar>giant spider>spider swarm(fully traited the lot.)
Thanks to the meta i got dokkalfar his last trait for more staying power, and then also traited out ancient horror.
This team uses about 6 different troops, only one of them is not guaranteed to be summoned when things go south.
Biggest threat, mercy.
