If an Attack Position monster you control battles an opponent's Attack Position monster with higher ATK, during damage calculation: The player who controls the battling monster with lower ATK can pay 500 LP, and if they do, their monster gains 500 ATK during damage calculation only, then repeat this effect until neither player chooses to pay LP. Neither player takes any battle damage from that battle, also send to the Graveyard, all cards on the field of the player(s) whose monster was destroyed by that battle, after damage calculation.
