If a Monster reaches 20 VP but a card then takes its VP below 20 or eliminates it, does it still win?
Best reading: no. A Monster must still hold 20 VP and survive its turn to win, so a later card that drops it below 20 or eliminates it takes the win away. The other reading treats the 20th VP as an instant win, but the rulebook's survive-the-turn rule points away from it.
