pokemon card shopping M6 Box} Storm Emeralda Trainer Form Is anything at my local

None of the one drop or two drop "Tap for any color of mana" things are cheap like Birds of Paradise or even things like Noble Hierarch that taps for three are cheap either

The cards played in World Championships Seattle in 1997 must look very different from the ones played in 2004 in San Francisco

The issue is that it is inconsistent (in theory you could buff just about any card to be good enough to see play, so where do you draw the line?), but the upside is this is the kind of thing that can be changed as often as necessary until they get it right

Shining: Included in Shining Legends [SM3+], these cards feature a Shiny Legendary or Mythical Pokmon

That'll likely stop it from being good enough, unfortunately
