Brokers Confluence
Instant
Choose three. You may choose the same mode more than once.
• Proliferate. (Choose any number of permanents and/or players, then give each another counter of each kind already there.)
• Target creature phases out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
• Counter target activated or triggered ability.

Rulings
If you choose the first mode and also the second or third mode as you cast Brokers Confluence and all targets are illegal as it attempts to resolve, you won't get to proliferate.
