Standar combination will be:
- Def down enemies
- Attack up allies
- Hit-all or hit-3, or with shared damage
- Heal
Practice slowly from rainbow team into 2-1-1-1, 2-2-1, 3-2, 4-1, and mono teams.
With stacking color, the big advantadge is:
- focus on less color tiles,
- the tiles resulting very big damage
- and so on and so on…
