Can you cast spells after other spells resolve but before the chain ends?

Ruling: Yes, you can cast spells after other spells resolve but before the chain ends. This is different from Yu-Gi-Oh and more similar to Magic: The Gathering's stack.

Sequence:

• When one part of the chain resolves, you can add back onto the chain
• There's a priority check from each player after each item is added/removed to the chain
• The spell being added must have reaction speed

Nuances:

• The ability to add to the chain after resolution requires the effect to have reaction speed
