Infinite Impermanence — Ruling

Regola generale

Regarding the『if you control no cards, you can activate this card from your hand』text:
This is not treated as an effect.
In addition to activating this card normally while it is Set, if there are no cards on your side of the field, you can also activate this card from your hand, by placing it in the Spell & Trap Zone.
This card can be activated this way during either player's turn.

About this card's ① st effect:
It cannot be activated during the Damage Step.
To activate this effect, target a face-up monster in your opponent's Monster Zone. However, you cannot target a non-Gemini Normal Monster (this includes Tokens), or a monster whose effects are already negated.
When this effect resolves, apply the『negate (the targeted monster's) effects』effect to it. Then, if you succeed in negating its effects this way, this card still exists in the Spell & Trap Zone, and was activated while it was Set, apply the『all other Spell/Trap effects in this column are negated』effect. (If the targeted monster's effects were not negated, for example because it is unaffected by this effect, you do not apply the additional effect.)
The column referred to by the『all other Spell/Trap effects in this column are negated』effect is the column that Infinite Impermanence is in at the time that its ①st effect resolves. After the ①st effect has resolved, and the『all other Spell/Trap effects in this column are negated』effect has been applied, if any Spells/Traps exist in that column (including ones that are placed there at a later point), their effects are negated.
