If I play Tideturner to an open battlefield (enabled by Miss Fortune's ability), do I get a conquer point before the ability triggers? And if I swap a teammate's unit to the same battlefield, does the teammate also get a conquer point?

Ruling: You do not score with Tideturner before its ability triggers. Scoring only happens after the showdown ends (when there are no chains and all players have passed on playing actions). Additionally, Tideturner has been errata'd and can no longer swap with your teammate's units.

Sequence:

• Play Tideturner to the battlefield
• Tideturner's swap ability triggers and resolves
• Showdown continues until no chains remain and all players pass
• Only then does scoring occur

Nuances:

• The original strategy is no longer possible due to the Tideturner erratum preventing swaps with teammate units
• Whether both teammates can score the same battlefield in one turn is unclear in the current rules, though there is debate about the intended interpretation
