Here is my idea for daily challenges and rewards. The premisis is Monday is trivial and it builds up to Sat which is Deadly. Sunday is fun day!!
Monday: Trival level 2 goons and a bad guy. Reward= 75 ISP. It is Monday you need a warm up before work preety easy
Tuesday: No 3* characters allowed. Easy level 2 characters and a goon. The Goon should feed the bad guys. Reward= 100 ISO
Wednesday: Handicap day Level Normal. You only get to choose 2 characters and have to defete 3. Reward= 25 HP
Thursday: win with a 1* 2* 3*. Level Normal opponent could be Juggs, Ares, Sentry. Reward Recruite token
Friday: Hard level opponent starts with boosts 3 to all AP and has Hood. Reward= 1000 ISO
Sat: Deadly basicly the end of the gauntlet would be fine. 295 Sentry, Hood, Daken? 295 Jugs, Venom, goon to feed red and purple? Reward 50 HP
Sund: Funday you are given a 166 level 3 character to run. Easy difficulty mix of characters.
If you complete the entire week of challenges you get an extra 1000 ISO
Other types of daily challenges could be 3 of a kind where we get to use all 3 storms/black widows/Wolverines.
The one: You choose 1 character and you get 3 of them to fight.
Speed: Win a match in 10 moves or less
Any other daily challenges you would like to see? Also would the rewards be appropriate to play for?
