Righteous Confluence

If a mode requires a target, you can select that mode only if there’s a legal target available. Ignore the targeting requirements for modes you don’t choose. Each time you select that mode, you can choose a different target, or you can choose the same target.

If the third mode is chosen multiple times, each of those modes represents a separate life-gaining event. For example, if the third mode is chosen three times, and you control Karlov of the Ghost Council (a creature with the ability “Whenever you gain life, put two +1/+1 counters on Karlov of the Ghost Council.”), Karlov’s ability will trigger three times, for a total of six +1/+1 counters.

No matter which combination of modes you choose, you always follow the instructions of a Confluence in the order they are written. If the same mode is chosen more than once, you choose their relative order as you cast the spell.
