Include these legendary girls in your deck:
- Lumberjack of Fairy Tale - skills recharge 3 gems faster
- Trapper of Bimbos - start the fight with 3 gems charged
- Armorer of Past mistresses - skills recharge 3 gems faster
- Mab of Pixies - start the fight with 3 gems charged
This is 12 gems advantage so far, so all of them are fully charged before the first turn. Add another light legendary with the skill of +100% damage or gem upgrade and a strong skill, and you will have a deadly deck.
Now imagine that team coming against you in the tower.
I really hate the direction of the development of this game. They've even killed out that small creativity what they had developed before (like +100% in return for slower charge). I didn't even logged in since the second day of this previous event.
