Rule 601.4

While announcing the choices of any modes, alternative costs, and/or additional costs as described in rule 601.2b, some options may be available to a player only if other choices are made that would normally be made later in that rule’s instructions. In that case, the spell’s controller may consider any other choices to be made in that step. If any such choices could allow them to choose a particular mode, alternative cost, or additional cost, they may do so. Example: Inscription of Abundance is a modal spell with kicker and the text “Choose one. If this spell was kicked, choose any number instead.” When announcing the chosen modes for the spell, its controller may choose any number of modes, even though choosing to pay the kicker cost is normally done later in the announcement process.
