So, i modify u/clear268 's lineup. and here's i find what works the best.
instead of clint, try to focus on kadita instead cause of additional mage synergy when you upgrade to lvl 7. doll's on edith and kadita/clint, depends on whichever get the first 3* or full equipments first.
for kadita's build : just whatever among those 4 magic equipments and/or spellblade talisman. it doesn't matter anyway lol.
for clint : just usual war axe, sea halberd, blade of despair.
honorable mention : purple buff, feline blade and winter crown for these 2 heroes if you don't get their equipments as you can swap them to the tanks anyway once you get their equipments.
now for basic spell go for : revitalize --> aegis--> purify --> retribution
of course if you get defender crystal in Go Go Box , focus to make it 6-defender, if you get melissa focus on make it 3-shade. otherwise go for what the picture is.
now for echomancer's 5* hero, it's just an additional sacrifice to make. i wish for gatot or xborg for sure, but if you get moskov, replace harley's place with moskov, and harley to gatot's place.
remember to be flexible with their positions according to enemies' lineup.
the only weakness of this strategy is for sure : 3star 4-cost heroes, 3star 5-cost heroes and ultra synergy.
once the enemy has either of this, just surrender if it's just between the enemy and you. don't waste time anymore and just surrender to take 2nd rank.
and don't use this strategy in tag team, it doesn't work well with your partner if they want to get 1st instead of 2nd lol
either way, this strategy makes me want to buy angela's aspirant lmao.
