3 Level 9 monsters If this card is Special Summoned: Destroy as many monsters with String Counters as possible, and if you do, draw 1 card, then inflict damage to your opponent equal to the highest original ATK among those destroyed monsters in the GY (your choice, if tied). Once per turn: You can detach 1 material from this card; place 1 String Counter on each face-up monster your opponent controls.
