Pretty complicated, both players can use this fieldspell, you can end up with with dead against OtC and such, why not a 3*D? Seems better even after the nerf, at least the opponent won't use your field spell to pull something against you
First off and that is personal taste. I would run Odion with this skill. Drop the pathfinders, Endymion and riryokus. Backrow defense is solid. Owl of luck is prefered for an incoming attack and flip favour over pathfinder wich can leave you defenseless.
Storm is needed. Don't give your opponent the opportunity to set something uo for himself. Think about using wild tornado for a combo.
I really didn't scolded you, your deck can be erased against any naturia, or redb deck, you have 5 cards only to get a field spell on, that can also be destroyed, and the field spell also can bring the enemy hard beaters, against a toon deck you will not be able to do anything, so add counter traps and spells, and a tip as person, don't ask anyone opinion if you don't want it
