1. Question

If Aiza.LEON is face-up in the Monster Zone and the opponent activates Pot of Sloth, how much damage does Aiza.LEON inflict?

The question is whether the damage is based on the number of cards that remain in the opponent’s hand when the effect finishes resolving, or on the total number of cards that were added to the hand by the effect.

For example, if Pot of Sloth adds 6 cards to the opponent’s hand, but 1 of those cards is subsequently returned to the Deck or otherwise leaves the hand during the same effect, does Aiza.LEON inflict damage for 6 cards or only the cards that remain?

2. Reddit Discussion

The discussion initially contained an incorrect interpretation suggesting that Aiza.LEON might inflict 900 damage only once for a single effect, regardless of how many cards were added.

Another commenter focused on the wording of Aiza.LEON:

“each time your opponent adds a card(s) to their hand by their card effect”

The important clarification came from a Reddit commenter identifying as a Judge.

According to that explanation, Aiza.LEON counts each card added to the hand by the opponent’s card effect, rather than simply checking how many cards remain in the hand afterward.

The Judge also explained that the calculation is performed after the effect has completely resolved. Cards that were added to the hand still count even if they subsequently leave the hand before Aiza.LEON’s damage is applied.

The discussion therefore gives the following example: if Pot of Sloth adds 6 cards to the hand and 1 of those cards is subsequently returned, Aiza.LEON still counts all 6 cards and inflicts 5,400 damage.

3. Summary of the Reddit Answer

Interpretation	Result
Damage is based only on cards remaining in the hand	Not supported by the Judge’s explanation
Aiza.LEON deals 900 damage for each card added by the effect	Supported by the Judge’s explanation
Cards that leave the hand afterward are excluded	Not according to the Judge’s explanation
Six cards are added, then one leaves the hand	5,400 damage

The Reddit Judge’s explanation states that Aiza.LEON counts the number of cards added to the hand by the opponent’s card effect. The cards do not need to remain in the hand when the damage is applied.

The explanation also distinguishes separate instances of adding cards. Sequential conjunctions are treated as separate instances for this purpose.

4. Conclusion

According to the Reddit Judge’s explanation, Aiza.LEON inflicts 900 damage for each card added to the opponent’s hand by their card effect.

The important point is that Aiza.LEON counts the cards that were actually added, rather than checking the opponent’s final hand size.

Therefore, if an effect adds 6 cards to the hand and 1 of those cards subsequently leaves the hand, Aiza.LEON still counts all 6 cards and inflicts 5,400 damage.

This conclusion is based on the Reddit discussion and the Judge’s explanation. It should not be treated as an independently verified official Konami ruling unless an official Konami source is found confirming the interaction.
