GEO-SEQUENTIAL,
*deck building; 6 of one card, 5 of another, then 4,3,2,1.
*this leaves 9 quantum cards for a full 30 card deck.
*this works well for upd, decks.
using these rules, i would only ban, water nymph, miracle, gravity shard, and earthquake.
this could be added as a speed build rule, or a team element tourney. i prefer always that decks are set and used during whole tourney.
