When Player B defends a battlefield that Player A contested first, does Player B score a point for conquering the battlefield if their unit survives?

Ruling: Yes, Player B gains a point for the Conquer. The defending player scores when they establish control after combat, even though they were not the player who applied Contested first.

Sequence:

• Player A moves to empty battlefield and applies Contested first
• Player B moves unit to battlefield during Showdown, becoming defender
• Combat resolves and B's unit survives
• B establishes control over the battlefield
• B scores a point via Conquer

Nuances:

• Rule 440.2.b explicitly states establishing control does not have to be the player that applied Contested to the battlefield
• Rule 442.1.b appears to contradict this but is likely a wording issue
• This ruling has been confirmed multiple times by Rioters
