Musical Sumo Dice Games — Ruling

Effetto 0

This card's effect is a Trigger Effect that activates in the Monster Zone. (It must be activated once during the Start Step of your opponent's Battle Phase.)
If the number of Xyz materials on this card is incremented from 6 (or fewer) to 7 (or more) by the resolution of its effect, you will win the Duel. (If this card gains its 7th material in any other way, you will not win the Duel.)
This card's effect must be activated even if this card is in an Extra Monster Zone.
If the monster in the chosen Monster Zone is unaffected by this card's effect, or if the Zone cannot be used, send this card to the Graveyard.
If this card does not exist in a Main Monster Zone when resolving its effect, that effect is not applied. (You do not roll a die.)
When this card's effect resolves, move this card directly to the resulting zone. (This card is only moved once, from its current zone to that zone. This card is not moved multiple times, corresponding to the resulting number.)
