Field Phase is the first phase of every battle. In Field Phase, the player can move in 3 dimensions (unlike in duel phase). The main goal of Field Phase is to switch the phase into Duel Phase so the opponent can deal more damage. In Field Phase, Y attacks are ranged attacks while X attacks are homing attacks, leading to mediocre damage output. It is much easier to switch the phase in Field Phase than it is in Duel Phase.
