1. Question

Heavy Slump states that if your opponent has 8 or more cards in their hand, they shuffle their entire hand into the Deck and then draw 2 cards.

The question is what happens if Heavy Slump is activated while the opponent has enough cards in their hand, but several cards are discarded as costs during the Chain, leaving their hand empty before Heavy Slump resolves.

Does shuffling zero cards into the Deck count as successfully performing the first part of the effect, allowing the player to draw 2 cards?

2. Reddit Discussion

The Reddit discussion concludes that the player does not draw 2 cards if their hand is empty when Heavy Slump resolves.

The important part is the connection between the two actions in the effect. Heavy Slump requires the player’s hand to be shuffled into the Deck before they draw 2 cards. If there are no cards in the hand, nothing can actually be shuffled into the Deck.

Because that first action does not occur, the subsequent draw does not happen. Several commenters reached the same conclusion.

One commenter also explained the interaction in terms of the word “then”: the second action depends on the first action occurring.

3. Summary of the Reddit Answer

Interpretation	Result
Heavy Slump resolves while the hand contains cards	The hand is shuffled into the Deck, then 2 cards are drawn
Heavy Slump resolves with an empty hand	Nothing can be shuffled into the Deck
Shuffling zero cards counts as performing the first action	No
The player can draw 2 cards despite having no cards to shuffle	No
The first action fails to occur	The effect stops before the draw

4. Conclusion

According to the Reddit discussion, Heavy Slump will not allow the player to draw 2 cards if their hand is empty when it resolves.

Although the activation was legal because the opponent originally had 8 or more cards, the game state can change before resolution. If the player’s hand has become empty, there are no cards to shuffle into the Deck. Since the effect says to shuffle the hand into the Deck then draw 2 cards, the draw does not occur.

The Reddit discussion provides a community explanation of the interaction rather than an independent official Konami ruling. The distinction between activation conditions and what actually happens during resolution is the central point of the ruling.
