all japanese pokemon cards Are Pokémon Worth More and Iron Leaves makes their debut as Pokémon ex Pokemon card GX Tag team

The alliance abilities work with casting creatures, creating tokens, and any other way a creature ETBs

Their silver border and acorn stamp show that they cannot be used in any legal play

Other creatures I like but can't find space for are Skullmulcher , a creature + sac outlet and card draw on a body, Green Sun's Zenith or Chord of Calling this guy out when your sac outlets have been removed or countered to finish of a player second main phase, remember it is a may ability so can still keep enough tokens out for defense if needs be

It's probably not coming back because shuffling effects were so common and that'd take a long, long time
