I have 2 things,
Finding Card Art for Card design tasks is super pointless and should not be required (royalty free clip art looks horrible and won't be put in the game anyway).
Masters tournament should be 20% (or whatever the rules for that will be) off-element cards, not a set amount - that's a lot more logical in every way, just not feasible for any tourney because you can't expect people to know elementary school math, but I think from Masters you can.
