Winning and Losing

Trinity ways to end the game:

• A Player loses when they have zero (0) or less life.
• A Player loses when they try to draw a card from an empty library.
• A Player wins when they earn a total of seven (7) victory points. Activating a Scene's Climax earns two (2) VP and Planeswalker's Ultimate three (3) VP.

Attacking and Blocking

Trinity between flying, subsurface, and neither (normal).

• Flying can only be blocked by other flying and by reach.
• Subsurface can't be blocked by flying.
• Consequently, a creature with both flying and subsurface can only be blocked by a creature with reach but no flying.
