Pretty surprised that someone bothered to fake Fusion strike and Battle Styles, to be honest. They're both extremely unpopular sets along with Chilling Reign due to bad pull rates. And, typically these fake products end up being used on Ebay/Mercari and other places to try and scam newbies these days. You can find Fusion Strike ETB's pretty often that are discounted down to $30-35 that still don't sell. And, Battle Styles booster boxes are available for around $80 on quite a few sites compared to the normal $115-130 price, because everyone and their geriatric grandma living in a nursing home dislike that set for having basically no chase cards.
