There is another thread on this board where someone is trying to come up with a format for Gen I and Gen II cards.
Unsurprisingly, it is difficult to get people to agree on which cards do or do not need to be banned, as
many cards were designed to counteract each other. Just not well, designed, so when you take out one obvious problem, it makes another one emerge. Cost is also an issue; any remotely competitive cards will skyrocket in price if you manage to convince TPCi to start using this for major events.
Can I suggest a
better approach? Convince the powers-that-be, for the
next major anniversary, to reprint some of the old cards.
No, not like
Generations. Also not a straight reprint either.
Instead, take the most problematic of the older cards, and reprint them balanced for the modern game. Issue errata for the older cards, or at least make it clear that the new replaces the old. Most Pokémon aren't going to be a problem,
but we can fix
Slowking (
Neo Genesis), we can fix all those old Trainers that really ought to have been Supporters, etc.
Yes, I am
still holding out for a Supporter named "
Professor" that will replace not only the original
Professor Oak but
Professor Juniper and
Professor Sycamore so we can get rid of that silly rule stating you can't run the two together. Just errata them all to make them the same card
and watch as fans love how we can now get Alternate Art promos featuring the many,
many minor Professor characters in the franchise!
