1. Question

The Reddit discussion asks whether Number 41: Bagooska the Terribly Tired Tapir, while in Defense Position, can negate monster effects that are continuously applying rather than being activated.

The specific point of confusion is Bagooska’s effect that negates the activated effects of Defense Position monsters. The question is whether this also affects passive effects such as a monster being unable to be destroyed by battle or card effects.

The original poster also noted that AI had suggested that these passive effects could be negated, which led to the question about how Bagooska’s effect actually works.

2. Reddit Discussion

The Reddit responses consistently distinguished between activated effects and continuous effects.

A Judge & Moderator explained that Bagooska does not negate continuous effects. The reason is that continuous effects do not activate and therefore do not create an activated effect for Bagooska to negate.

Another commenter explained the distinction in terms of Chain activation: effects that activate can be identified by activation conditions and/or costs in their text, while effects that do not start a Chain cannot be negated by Bagooska’s effect.

Other commenters made the same basic distinction, stating that passive or continuous effects do not activate and therefore are not affected by Bagooska’s negation effect.

One additional response described the timing of Bagooska’s negation: a monster effect that was activated on the field while that monster was in Defense Position is negated when that effect resolves.

3. Summary of the Reddit Answer

Interpretation	Result
Bagooska negates activated monster effects	Yes. Its effect applies to monster effects that activate while the relevant monster is in Defense Position.
Bagooska negates continuous effects	No. Continuous effects do not activate, so they are not the type of effect Bagooska negates.
A passive effect such as “cannot be destroyed by battle or card effects” is negated	No, if the protection is a continuous effect. It does not activate and therefore is not negated by Bagooska.
An activated monster effect that changes something about the game state	Potentially yes. If it is an activated effect that meets Bagooska’s conditions, Bagooska can negate it.

The key distinction is therefore not whether an effect is “passive” in everyday language, but whether the effect is an activated effect that starts a Chain. The Reddit discussion repeatedly identifies continuous effects as effects that do not activate.

4. Conclusion

Bagooska does not negate continuous effects.

Its Defense Position effect concerns activated monster effects. A continuous effect that is simply applying on the field does not activate, so there is no activation for Bagooska’s effect to negate.

Therefore, a monster whose protection is provided by a continuous effect, such as an effect preventing it from being destroyed by battle or card effects, would not lose that protection merely because Bagooska is applying its negation effect.
