The use of the
flicker mechanics from some of the cards don't have nearly enough targets before cmmdr is out. Maybe find some cards that
flicker more than once when you do some action, rather than just once per card.
However, the
landfall can come in clutch in some scenarios, a very good support role.
Please go through and remove most of the colorless lands, they are terrible to play in a 3 color deck. They only work best in artifact or decks that can use that only need colorless.
Otherwise, fun deck to play with.
