Why is deck thinning considered a strategic move in Riftbound?

Deck thinning is strategically significant in Riftbound primarily because it enhances the overall consistency of one's draws, allowing players to encounter their most powerful or essential cards more frequently. When a player removes less effective cards from their deck, they increase the probability of drawing cards that are more critical to their strategy.

While choice C mentions focusing on core card strengths, which is a valid aspect of deck thinning, the primary advantage lies in drawing the stronger cards more reliably rather than just reinforcing the strengths of a core card. By streamlining the deck, players can ensure they are more likely to access the key components they need to execute their strategies effectively, leading to a more reliable game plan overall.

The other options touch on various aspects of gameplay but do not capture the essence of why deck thinning is effective. For instance, while it might seem that increasing the likelihood of drawing cards faster could be a result of deck thinning, the key idea is that it ensures those draws are more impactful. Reducing the total number of cards in play or increasing the number of spells used does not directly tie back into the strategic advantage of drawing the core components consistently, which is at the heart of the value of deck thinning.
