During Your Main Phase (Lv. 1-2): When this Spirit is sacrificed for a Tribute Summon, you can instead exhaust this Spirit to bring the Tribute Summon Spirit to the Field without paying its Tribute Cost. During Your Opponent's Attack Phase (Lv. 2): As long as you have fewer Spirits on the Field than your opponent, all "Imaginary Beast" Attribute Spirits on your Field are upgraded to their highest Battle Level.
