More questions for the returning noobie:
Does rainbow count as an element?
If you use
to refer to the "Other" cards (such as quantum pillars), they are technically not an element, so they do not count as one for the purpose of this tournament.
What is the minimum number of cards needed to be considered using 3 elements? (3 of a single card from the element from the list? Can I use ppms as the 3rd element?)
Yes, 3 copies of a single card type is sufficient to be considered using that element.
Yes, you can use PPMs as the 3rd element.
