In a match between an experienced player (A) and a new player (B), Player A plays Icathian Rain and announces targets immediately (knowing they should be chosen on resolution). Player B plays Discipline on one of those targets. Player A then tries to change targets after Discipline resolves, claiming the original targets weren't locked in. What is the correct ruling?

Ruling: Player A receives a warning for angle shooting. Player A must adhere to their originally announced targets when Icathian Rain resolves, and Discipline resolves normally. No rewind occurs because Player A gained new information from seeing Discipline played.

Sequence:

• Player A announces targets while playing Icathian Rain (as a shortcut)
• Player B plays Discipline on one of the announced targets
• Discipline resolves
• Icathian Rain resolves with the originally announced targets (Player A cannot change them)

Nuances:

• This is considered angle shooting because Player A knew the rules and intentionally misrepresented when targets are chosen to gain an advantage against a less experienced player
• Player B did not need to explicitly interrupt the shortcut by stating the exact timing; playing Discipline in response is sufficient
• If Player A repeats this behavior, it warrants a game loss
• The situation borders on cheating given Player A's knowledge of the interaction and intentional exploitation
