Giant Ballpark - SOFU-EN062 Common Unlimited

During damage calculation, if a player would take battle damage: You can make neither player take any battle damage from that battle, and if you do, send 1 Level 4 or lower Insect monster from your Deck to the GY, then, if you sent a Normal Monster this way, you can Special Summon any number of monsters with the same name as that monster, from your hand, Deck, and/or GY. If a monster(s) you control is sent to the GY by an opponent's card effect (except during the Damage Step): You can Special Summon 1 Insect Normal Monster from your GY. You can only use each effect of "Giant Ballpark" once per turn.
