"Definite Dodge" should be a new move for swap in dodge creatures so they get the full advantage of getting no damage on swap in. So this would be 100% dodge of 100% damage unless your opponent uses an ability that removes positive affects.
"Definite Dodge" could also be an instant move on some slower creatures with fewer hit points where you anticipate your opponent doing a big damage move and it takes no damage. It’s like 'Instant Invincibility" except it deflects all damage including shield breakers. Although it can be removed with the remove positive effects so it would not be totally invisible.
