Triple Play Challenge: Your deck cycle is split into batches of three cards. You must play the three cards in a batch before the next batch of three is drawn for you.

Infinielixir Challenge: The Elixir bar remains full permanently, which means that the only thing stopping you from spamming cards is the cooldown between drawing cards. Fill your deck with heavy units and spells, this can get chaotic!

One Win Challenge: A high-stakes challenge where you only need one win for the top prize, but only need one loss to lose. The consolation prize for losing is much more severe than any guaranteed prize (20 Gold and 1 card). The entry cost is 50 gems. The top prize is half the expected winnings of a Grand Challenge chest (given a 50% win rate) (the expected winnings are yet to be calculated but I'll probably post it here when I do find it).
