Same question as above. And also are flying weapon decks fine to use?
Three weapons are banned (fahrenheit, arsenic, discord) but if you can make it work with the oracle circle thing, then yeah, you could. For instance, you could do flying owl's eyes or flying daggers in a monoair. Air is next to water, so you could do a duo with flying tridents, or if you included at least 3 water cards, a trio with flying druid staffs. To use flying titans, you'd need at least a quintet under these rules, since air and gravity are 5 spots away from each other.
