I have a team that can win most games within 2 minutes and bring in between 50-90 souls (with VIP 10 and deathknight/celestial armors, VIP 0 brings in between 35-75 souls) there is a a bit of investment needed for this though (equivalent to a legendary dual mana troops 3rd trait).
The hero class “Necromancer”'s third trait grants a single soul with 4+ of a kind matches (2 souls with a 100% armor or 100% VIP level (3 souls for both))
This team is based around the hero weapon “Cresendo” I will list an alternative team in the event that this weapon is not available to you at the end.
“Green Giant’s Song”
Green Seer (x)
Giant Spider (2+)
Hero (Cresendo)(Necromancer)(Magic Perk)
Alchemist doesn’t overlap with any other troop so if he alone is frozen the remaining troops are unaffected, he can also cast his spell to power up Green Seer in a pinch. Green Seer fill up in just 2 unserged purple matches of any size (a total of +2 bonus for purple through Giant Spider’s magic link and the purple banner for 5 mana on 3 of a kind purple matches) and can start the loop for which the team will win. Giant Spider fills on the green that Green Seer produces and produces purple for him in return. The over fill from either troop in this loop goes to the Hero’s Cresendo which will deal a rather decent chunck of true damage to the entire enemy team. As early as its 2nd cast but typically no later then its 3rd cast it will also net an extra turn as it starts picking off enemy troops, after the first troop falls the others usually go in the same turn (except in special circumstances).
With all of the conversations the 1, 2, or 3 souls per 4+ of a kind quickly add up and if anything it adds a change of pace for the game. (Note that even more souls can be gained in casual/explore/challenge modes via Difficulty bonuses)
