How does immediate resolution work for Units and Gear, and what happens when a Unit is played as a reaction in a chain?

Ruling: Units and Gear resolve immediately when played - they cannot linger on the chain. As soon as all choices are made and costs are paid, they immediately resolve and enter play. After a permanent resolves, the player who controls the next item on the chain gains priority.

Sequence:

• Player A plays an Action Spell
• Player B responds with a Unit (e.g., Shen)
• The Unit immediately resolves and enters play (cannot be responded to)
• If the Unit has no play effects, Player A gains priority (they control the next chain item)
• If the Unit has play effects (e.g., Teemo, Strategist), those effects go on the chain after the Unit resolves, and Player B retains priority

Nuances:

• Units and Gear can never be countered by spells because they don't linger on the chain long enough to be targeted
• Play effects trigger and go on the chain after the Unit/Gear has fully resolved
• This applies to Units played from hidden zones as well (e.g., Blastcone Fae)
