- Added a more conservative version of AILogic PayEnergy for PutCounter AI that only pays energy if the creature is in combat (attacking/blocking) or if there's more energy available than the most expensive energy cost of a permanent SA on the battlefield requires plus whatever the PutCounter SA requires.

- Set this logic for Longtusk Cub and Bristling Hydra.
- TODO: maybe somehow teach the AI to pay energy if it can save the creature from lethal damage from a spell?
