What is the primary benefit of card synergy in Riftbound?

The primary benefit of card synergy in Riftbound lies in its ability to enhance the effectiveness of unit and spell combinations. When cards work together effectively, they can create powerful interactions that elevate their overall impact during gameplay. For instance, certain spells may amplify the abilities of specific units, or combinations of cards could trigger additional effects that lead to more strategic advantages. This synergy allows players to formulate intricate strategies that leverage the strengths of their cards, ultimately leading to more effective plays and a greater chance of victory.

The other options do not align with the core advantage of card synergy. Increasing randomness would detract from strategic planning, whereas playing more cards each turn doesn't inherently improve the power of those cards in relationship to one another. Simplifying strategy could detract from the depth and enjoyment of the game, which is built around the interaction and synergy of the cards. Thus, the focus on enhancing the effectiveness of combinations is what truly underscores the value of card synergy in Riftbound.
