If Tiana Crownguard prevents a player from gaining a point, can they still trigger Conquer effects and/or draw a card (when at 7 points)?

Ruling: When Tiana Crownguard prevents you from scoring a point, you still "score" the battlefield and trigger Conquer effects, but you cannot draw a card when at 7 points because the draw requires actually gaining the point.

Sequence:

• Player attempts to Conquer a battlefield while at 7 points with Tiana in play
• The point gain is prevented by Tiana
• Conquer effects still trigger (confirmed 100%)
• The card draw does not occur because you didn't actually score the point

Nuances:

• The distinction between "scoring" (the act of Conquering/Holding) and "scoring a point" (gaining the actual point) is critical
• Conquer effects trigger even when the point gain is negated
• The draw-a-card effect at 7 points requires actually gaining the point, not just attempting to score
