Does Petricite Monument's effect that gives units Deflect persist after the gear leaves play?

Ruling: Petricite Monument's effect is only active while the gear is on the board. When the gear goes to the trash, units lose the Deflect keyword.

Nuances:

• The effect does not persist for the rest of the game
• The effect does not apply only to units that were on the field when it was played
• The effect is an ongoing aura that applies to units while the gear remains in play
