Rage Challenge: The whole Arena is affected by Rage. LET'S GET READY TO RUMBLE!

Underused Cards Challenge: You must build a deck out of the 20 cards with the lowest use rates.

Blind Chest Challenge: At the start of the battle, you're given a Draft Chest which gives you eight pairs of two cards. Pick one, trash the other. That's your deck. Rewards are also given as a Draft Chest but they're completely normal otherwise.
