Can you pay the accelerate cost when playing a unit with accelerate from a location other than your hand without paying costs (e.g., with Baited Hook)?

Ruling: Yes, you can pay the accelerate cost when playing a unit with accelerate from outside your hand without paying costs. When you ignore a cost, you only ignore the base cost, and the unit goes through the full process of play including choosing optional costs.

Nuances:

• Effects that let you play cards "without paying costs" only ignore the base cost, not optional costs like accelerate
• The unit goes through the complete play process, which includes the option to pay accelerate
