1. Question

A Reddit user asked whether Ash Blossom & Joyous Spring can be activated in response to Book of Eclipse while Droll & Lock Bird is applying.

The confusion comes from the fact that Droll prevents players from adding cards from the Deck to the hand. Since Book of Eclipse includes a later part that allows cards to be drawn, the question is whether Ash Blossom can still be activated when that part of Book of Eclipse cannot successfully happen.

The question was also prompted by a related interaction involving Diabellstar Vengeance and Ghost Belle & Haunted Mansion, where an effect’s activation legality depends on what the activated effect actually includes.

2. Reddit Discussion

The main Reddit answer was that Ash Blossom can be activated in response to Book of Eclipse even while Droll & Lock Bird is applying.

The explanation focused on the difference between what an effect includes and whether every part of that effect can successfully resolve.

Book of Eclipse has an immediate part that changes the battle positions of monsters. It also contains a later action involving drawing cards. According to the Reddit discussion, the fact that Droll prevents that later action from successfully occurring does not remove it from the effect itself.

Ash Blossom checks whether the activated effect includes an effect that adds a card from the Deck to the hand. It does not require that the opponent must actually be able to perform that action successfully.

One commenter used Bystial Magnamhut as another example. They explained that Magnamhut can still activate an effect that includes a Deck-related action even when another restriction makes that action impossible, and Ash Blossom can still respond to that activation.

Another commenter summarized the principle by explaining that Ash Blossom and Ghost Belle do not determine activation legality by checking unrelated effects that would prevent one of the listed actions from succeeding.

The original poster therefore accepted that the explanation involving Book of Eclipse’s wording was consistent with the broader reasoning.

3. Summary of the Reddit Answer

Interpretation	Result
Book of Eclipse is activated while Droll & Lock Bird applies	Book of Eclipse can still be activated
Droll prevents drawing cards from the Deck	This does not remove the Deck-related part from Book of Eclipse’s effect
Ash Blossom checks whether Book of Eclipse includes a relevant Deck-to-hand effect	Yes
Ash Blossom can be chained to Book of Eclipse	Yes
The relevant effect being impossible to perform guarantees Ash cannot activate	No

The important distinction is between activation legality and whether an effect can successfully perform every part of its resolution.

Droll & Lock Bird can prevent a particular action from occurring, but that does not necessarily mean another card cannot respond to the activated effect based on the text that effect contains.

4. Conclusion

Yes, Ash Blossom can be activated in response to Book of Eclipse while Droll & Lock Bird is applying.

The Reddit discussion’s reasoning is that Ash Blossom looks at whether the activated effect includes an effect that would add a card from the Deck to the hand. It does not require that the player will actually be able to perform that action when the effect resolves.

This illustrates an important Yu-Gi-Oh! rules principle:

An effect can still contain a particular action even when another card effect prevents that action from successfully occurring.

Therefore, Droll & Lock Bird does not make Book of Eclipse lose the relevant Deck-to-hand component for purposes of determining whether Ash Blossom can respond.

This Reddit discussion provides a community explanation rather than an independent official Konami ruling. For authoritative TCG rulings, official Konami rules and ruling documents take precedence.
