For Garbage Grabber, is 'Recycle 3 from your trash' part of the cost to draw 1, or does the 'Do as much as you can' rule apply so you only need to pay 1 Energy and exhaust to draw 1?

Ruling: Recycling 3 cards from your trash is part of the cost to activate the ability. You must be able to recycle 3, pay 1 energy, and exhaust Garbage Grabber in order to draw 1 card.

Nuances:

• "Do as much as you can" (DAMAYC) applies to resolution of effects on the chain when targets are killed/moved or other changes happen between when the spell/ability finalizes and resolves, not to paying costs.
