The next group of cards that can sell for a lot is the rare holographic Pokmon cards from classic expansions
What I like about this: Suitable for older cards and collectors looking for long term value
I almost always prefer the former method because if ink gets pulled when you take the tape off, its far easier to patch up a black border than color-match and patch the back of the card and if your sleeves arent opaque on the back, a noticeable paint job will disqualify a card in tournaments (and it is noticeable)
It worked by using Kami of Whispered Hopes and Sleep-Cursed Faerie to ensure one of the two (or another creature) had both the untap ability and the mana producing ability to create infinite mana, and then the ability of Realm-Scorcher Hellkite to burn them to death
But worry no more, Ichiba Japan is born to help you avoid this kind of things
Its not the most powerful card in the world, but I could see it being useful in a Peasant Cube or Battle Box to reward players for dipping into multiple colors, plus the activated ability serves as a long-term win condition
