it changes with the seasons, and also with the developments in my roster. sorry, it’s gonna be a long one haha.
for a while, it was my yellow team: Leonidas, Guardian Jackal, Joon, Drake Fong, Mist. super fast, can take out enemies quickly, and if i get another match or just a single tile in a lot of cases, Leonidas can follow up with whoever is left, or can buy me some time with his mana cut. 40% mana reduction!!
then it was my purple team: C. Rigard, Kageburado, Myztero, Ametrine, Tiburtus with CB. i put the two 11 mana troops on Rigard and Tiburtus (my only mana troops at the time), and everyone charges in three matches (Ametrine, sadly, would still only be at charge 1, however). i used to put the mana troops on Kage and Myztero for the 6-tile charge, but i got a lot more success putting the mana troops on the wings with that mana bonus from the costume, and everyone fires in 9 tiles. and i will never get tired of firing a bunch of status ailments back with Myztero!
then my fire team was ole reliable for a while: Boldtusk, Vanda, Marjana, Gravemaker, Mitsuko. no matter how much my roster changes, i will never get tired of watching ice heroes kill themselves on Mitsuko’s reflect, and i have also had the pleasure of seeing a charge 1 Cobalt kill himself despite his high bypass chance!
in the last 5* buff booster tournament we had, i fell in love with this blue team: C. Kiril, Sonya, Fenrir, Magni, Raffaele. Raffaele has bailed me out of so many jams. i had previously used C. Magni and base Kiril, but i discovered a few weeks ago that switching which costume i use turns out to be more effective. not only that, but during that tournament with so many Krampuses running amok, i discovered this team actually has a kind of “double dispel” effect on Taunt heroes: Sonya can knock out Krampus’s Taunt, and then C. Kiril can follow up to negate the attack boost. this team was kind of floundering for a while because Sapphire and Boril would take turns in Fenrir’s spot, and then i saw the light on Fenrir. kills are consistent now, and Fenrir charges quickly for follow-ups because of mana from kills.
now, i have two favorites: a green team with C. Melendor, Lianna, Elradir, Caedmon, and Almur; and a yellow team with Guardian Gazelle, C. Vivica (still at 3.70), Gullinbursti, Mist, and Norns. i raided to global 7 with the green team because putting the 11 mana troop on Elradir makes him charge in 3 matches plus one status ailment. that elemental link of free mana is so clutch for follow-ups. the yellow team is slow, yes, but getting Vivica and Gulli to fire almost always guarantees the whole team is overhealed, and the reduced damage from Gazelle’s Dance of Spirits buys me time to get yellow tiles to kill yellow heroes because Norns makes them weak to them!
i do have some other teams i use in war that i like and in other situations, but these are my all-time favorites.
