For example, popular Mega Evolutions: Ascended Heroes boosters sell for 17 per pack, instead of the 10 per pack found from other retailers
Every booster pack contains the following: 6 Common Cards 3 Uncommon Cards 2 Rare or Better* Cards 1 Foil Card of any Rarity The Rare or better cards have a chance of being Rare, Super Rare, or Legendary, but will never be Enchanted
Treasure Cruise + Dig Through Time Any mechanic that lets you pay mana costs with a resource other than mana is at least a little broken
It's worth noting, at this point, The Pokemon Company hasn't confirmed when or how these will be making their way to the English-language version of the TCG, if at all, but you have to assume it will be part of another set of collection boxes
The main downside comes from the floor: Loot does nothing without a bunch of other permanents in play and gets a nice, fat target painted on its head whenever you cast it
