A.I.'s Show (BROL-EN042) [Brothers of Legend]

While you control a Link-3 or higher "@Ignister" monster in the Extra Monster Zone, when an opponent's monster declares an attack: Special Summon from your Extra Deck any number of non-Link Cyberse monster(s) with 2300 ATK, whose combined ATK is less than or equal to the attacking monster's ATK, then end the Battle Phase.
