I'll talk about the other mode that was added: Blessed Gardens.
These are like standard maps, but with a twist. Recently, new features were added: Legendary Heroes and Blessings. What these do are Legendary Heroes have an element assigned to them, (Water, Earth, Fire and Wind) and they give bonuses to units with blessings. Blessings are items you can assign to units to give them the bonuses from Legendary Heroes. If you make a team with a Legendary Hero and 3 units with the same blessing as the LH, they get the bonuses.
The twist with the Blessed Gardens are sets of challenge maps divided among different elements. In order to clear them, you can only use Legendary Heroes and heroes with the required blessing. You'll be given a set of 4 water blessings to start, which you can build a team and clear the Garden of Water 1st. You'll earn blessings for the next Garden, which you can build a team for the next one as well.
These maps are good to do if you want orbs, as well as other rare resources.
And that should cover the new features. Hopefully these explanations help.
Dance my pretties!
