Giant Ballgame (MP24-EN325) [25th Anniversary Tin: Dueling Mirrors]

During your Main Phase, if this card was activated this turn: You can Special Summon 1 Level 6 or lower Insect monster from your GY. You can reveal 1 Insect monster in your hand, then target 1 face-up monster your opponent controls, and 1 Insect monster you control with less ATK than the revealed monster; switch control of those monsters, and if you do, the monster you took control of becomes an Insect monster. You can only use 1 "Giant Ballgame" effect per turn, and only once that turn.
