Can a player avoid distributing lethal damage during a showdown if they are capable of doing so?

In the context of the game, when a player engages in a showdown, they are often required to adhere to specific rules regarding the assignment of damage. If a player is capable of dealing lethal damage, the mechanics of the game typically mandate that they do so. This reflects the principle that a player should actively engage in combat and confront the threats posed by opposing units.

The necessity to assign lethal damage encourages strategic gameplay, fostering a dynamic and competitive environment. Each unit has inherent power and toughness values that determine their effectiveness in combat. If a player has the opportunity to deal lethal damage to an opponent’s unit, failing to do so would not only be contrary to the game's rules but could also undermine their chances of victory.

Regarding the other choices, opting not to assign lethal damage would contradict the essential mechanics of showdowns, as it would be a missed opportunity to eliminate opposing units and gain a significant advantage. The stipulations regarding the number of units and the involvement of other players also do not directly influence the imperative to assign damage when possible.
