The following sets had first edition print runs: Base Set Fossil Set Jungle Set Teamp Rocket Set Gym Heroes Gym Challenge Neo Genesis Neo Discovery Neo Revelation Neo Destiny You can also find a "shadowless base set" edition for the first Pokemon set that is considered very rare
It's easy to stack counters on a creature with cards like the partners Halana and Alena, who can put +1/+1 counters on a creature for free
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
Weve seen plenty of cards that do the opposite, like Blood Moon and Price of Progress, but never anything like this
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
