As a side effect, most Pokmon in the anime have moves that deal in both short and long-range combat, even if the Pokmon in question would only be effective with one of them in the games: For example, Team Rocket's Mimikyu knows both Shadow Ball (for long-ranged combat) and Shadow Claw (for short-ranged combat) despite being mainly a physical attacker in the games (and thus would normally only have Shadow Claw, which uses its physical attack)
If the ability creates one or more token creatures, those creatures wont be able to attack that turn (unless they gain haste)
Conversely, Reverse Holos apply the mirror finish to the entire card frame *except* the illustration window itself
It is consistently stunning
Every mana creature, utility creature, and nearly every token creature will be coming our way at the suddenly inexpensive-sounding amount of seven mana
While many are collectors, there are others who plan to re-sell particular cards for an exorbitant amount of money
