Will be nice to also add a currency a token it for any piece of gear/card/minion/crafting material and/or an exclusive reward.

For example 5 token for a chest piece, 10 for a minion, 3 for gloves, 30 for a mount, etc.

I think will be a good way to keep people doing this daily even if they no longer have any class to level. Also, will help to finish a full set since the last piece you need never drop or to obtain that one minion you really want but never won the roll.
