Challenge mode possibilitys ?

[Agreus]

Just wanted to say I really love the challenge modes.

While playing the hyper surge challenge I thought that more challanges that encourage you to pick certain themes or teams could be a nice way to get people to try new team comps that they didn´t think abaout.
I know people that once they found something that works they always try to come back to the same setup and I myself often overlook certain things for example it took ages for me to try a stun team instead of always going for pure shock-stacks.
As a bonus this could be a nice way to ease people that are new to this kind of game into possible team-setups and synergies.
