Can you tap a resource to add energy/power as a reaction, and if so, what happens with priority and can opponents respond to it?
Ruling: You can tap a resource to add energy/power as a reaction, and it cannot be responded to. However, this is effectively pointless because priority passes to the opponent after it resolves, allowing them to play reactions anyway - the same outcome as if you hadn't done it.
Sequence:
- Player taps resource to add energy/power as a reaction
- This ability is added to the chain and cannot be responded to
- The ability resolves
- Priority passes to the opponent
- Opponent can continue adding to the chain
Nuances:
- The "unreactable" nature of adding energy/power doesn't prevent the opponent from playing reactions afterward - they simply aren't reacting to the resource tap itself, but can still add to the chain
- A player can use any amount of reactions before passing priority
- You can force a cleanup with this, but that's about the only purpose
