How do Gears work in Riftbound? Do they stay on the battlefield until destroyed or are they one-time use?

Ruling: Gears are played into your base and remain on the battlefield until something sends them to the trash. When you play a Gear, you get its on-play effect, and any continuous effects remain active as long as the Gear stays on the field.

Sequence:

• Play the Gear into your base
• Resolve any on-play effects when played
• Continuous effects remain active while the Gear is on the field
• Gear stays on the battlefield until removed by a game effect

Nuances:

• Gears do not need to be attached to units; they exist independently in your base
• Hidden Gears like Zhonyas do not have proper rulings defined yet
