Alternate Holographic. there is 1 AH per booster, and it's a random card from the set, but cannot be an EX or Shining. Before Hidden Legends, they were Reverse Holographic, with the text being holographic instead of the picture. Since HL, they've been tampering with different styles of holographic tints on the pictures, and have seemed to come to a consensus of an Energy-inspired background with the set name in the LR corner of the picture.
