I ain’t reading through all of the replies, but I imagine this has been said somewhere up above: Yu-Gi-Oh! is a manga/anime/card game. Pokemon is the world’s largest multimedia franchise.
Pokemon has a lot of characters, but they’re developed and fleshed out across all of the different games, shows, etc. It is easy to make a card for any Pokemon as people like and recognize them. Casuals and non-players can easily partake because they know the characters.
YGO introduces new characters with every set. The manga and anime are not nearly as popular as Pokemon. Casual fans only know the old shit like Dark Magician, Blue Eyes, Red Eyes, Exodia, Egyptian Gods, Elemental Heroes, Stardust Dragon, etc. YGO can release reprints/rehashed versions of these cards with each set, and they do, but pulling “Exodia, the Legendary Defender” does not hit the same as pulling plain 'ol " Exodia the Forbidden One".
“Charizard ex” is still a Charizard. People recognize this and get excited.
“Blue-Eyes Malefic Dragon” is not the same as the OG Blue-Eyes (this example is very dated).
Edit: I often find myself wondering not “Why did YGO not comeback like Pokemon?” but rather “Why is YGO still alive?”.
I swear, the only stuff that I see at Target and elsewhere are reprint/anniversary-related products. Obviously, card shops will carry regular YGO sets but the big box stores seem to focus on nostalgia products and they always seem to have the same theme/gimmick (either anniversary-oriented or character oriented). As a kid, I got my YGO packs from big box stores and so not seeing regular packs at Target makes me question how the game is surviving without younger people getting into it.
