① Once per chain, during your Main Phase or your opponent's Battle Phase,
if your opponent has cards in their combined hand/field than you (Quick):
You can detach 1 Material from this card;
destroy all other cards on the field, also, for the rest of this turn, your opponent takes no damage.
● This is a Quick Effect.
Quick Effects are Fast Effects.
● When this card is successfully summoned, if nothing is triggered,
you can activate this card's fast effect before your opponent can activate any fast effect.
EG: When this is summoned, you can activate its effect before your opponent can use "Bottomless Trap Hole". Then, as Chain Link 2, Bottomless can be chained.
