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
