Does a countered card count toward satisfying Legion requirements?

Ruling: Yes, a countered card does satisfy Legion requirements as long as it completes the Finalized step in the chain process.

Sequence:

• When a card is played, it goes on the chain as a Pending Chain Item
• The card becomes a Finalized Chain Item (targets chosen, costs paid)
• Players have opportunity to play Reaction cards (including counters)
• If countered, the card is removed during the Pass/Resolve step

Nuances:

• Legion specifically checks whether a card has been Finalized (Rule 812.1.c), not whether it resolved
• Countering happens AFTER finalization, so the Legion condition is already met
• This differs from other "when you play" effects which may require full resolution
• Hiding a card is not playing a card and does not satisfy Legion
