The Dalek Emperor — ruling 1

When a player faces a villainous choice, they first choose one of the two options, then all actions in the chosen option are performed.

The Dalek Emperor — ruling 2

If a spell or ability requires multiple players to face a villainous choice, the result is a little different from other effects in Magic. In that case, the first player in turn order makes their choice and the action for that choice is performed before the next player makes their choice. Then each of the remaining players repeat this process in turn order.

The Dalek Emperor — ruling 3

A player facing a villainous choice can always choose either option, even if one or both of the options are impossible. For example, if one of the options is to sacrifice a creature, a player who controls no creatures can still choose that option.

Official card text

Affinity for Daleks (This spell costs less to cast for each Dalek you control.) Other Daleks you control have haste. At the beginning of combat on your turn, each opponent faces a villainous choice — That player sacrifices a creature of their choice, or you create a 3/3 black Dalek artifact creature token with menace.
