1. Question

The question concerns Ryzeal Cross, a Ryzeal Xyz monster with Incredible Ecclesia, the Virtuous attached as material, and The Dragon That Devours the Dogma.

The opponent activates the trigger effect of The Dragon That Devours the Dogma while there is no Ecclesia monster on the field or in either GY.

Ryzeal Cross can respond by detaching Ecclesia as material and, if it does, negate the activated effect. The question is whether Cross successfully negates the effect.

The complication is that The Dragon That Devours the Dogma is unaffected by other card effects while an Ecclesia monster is on the field or in a GY.

The issue is therefore when the Continuous effect checking for Ecclesia begins to apply during the resolution of Ryzeal Cross.


2. Reddit Discussion

The Reddit discussion identified two competing interpretations.

One interpretation argues that Ryzeal Cross successfully negates the effect. The reasoning is that Cross’s effect performs the detachment and negation as a simultaneous conjunction. Because Continuous effects generally do not begin applying partway through such a simultaneous conjunction, the Dragon should still be affected by the negation when Cross applies it.

A Judge commenter explained that the interaction is complicated and depends on the type of conjunction involved. They noted that some Continuous effects can begin applying during sequential effects using wording such as “then,” while this generally does not happen during simultaneous conjunctions using wording such as “and.” Based on that distinction, they would personally rule that Cross negates the Dragon’s effect, although they explicitly stated that they could not find a direct ruling and were not completely certain.

Another commenter independently agreed with this interpretation, reasoning that Cross applies its negation before Ecclesia technically reaches the GY.

A different interpretation argues that the Dragon becomes unaffected as soon as Ecclesia reaches the GY, meaning Cross’s negation would fail. One commenter stated that Ecclesia reaches the GY before the negation is applied and therefore the Dragon should be unaffected by Cross at that point.

The discussion also included comments suggesting that simulator behavior could be tested, but another commenter emphasized that simulator behavior should not itself be treated as a ruling source.


3. Summary of the Reddit Answer

InterpretationResult
Cross’s detachment and negation are treated as a simultaneous conjunctionThe Dragon is negated
Ecclesia reaches the GY before Cross applies the negationThe Dragon becomes unaffected and is not negated
Simulator testingNot an authoritative ruling source
Judge interpretationLeans toward Cross negating the Dragon, but explicitly uncertain

The discussion therefore leans toward Ryzeal Cross successfully negating the Dragon’s effect, but it does not establish a definitive official ruling.


4. Conclusion

The Reddit discussion leans toward Ryzeal Cross negating The Dragon That Devours the Dogma.

The key argument is that Cross performs detaching Ecclesia and applying the negation as a simultaneous conjunction. Under the Judge commenter’s interpretation, the Dragon’s Continuous protection does not begin applying in the middle of that simultaneous conjunction.

However, the discussion also contains a directly opposing interpretation, and the Judge commenter explicitly stated that they could not find a direct ruling and were not completely certain.

Status: Community interpretation — unresolved.

No official Konami ruling is established by the Reddit discussion itself. Therefore, this interaction should not be presented as a confirmed official TCG ruling without an authoritative Konami source.
