Vylon Beta
After Mecha Phantom Beast O-Lion was banned, players quickly discovered this was one of, if not the best, tuner to summon with Crystron Halqifibrax to make Mecha Phantom Beast Auroradon, due to how easily this card could be looped from the GY.
Deskbot 001
This is probably the most infamous Field Spell with a gambling effect, since it only ever appears in incredibly long and janky FTKs
Light Barrier
One of the most famous, and powerful, retro cards of all time, this card made its anime debut in Duel Monsters, used by Bandit Keith, and wouldn't be seen again until GX, when Jaden uses it.

This is the only Elemental HERO with a coin toss effect
Elemental HERO Chaos Neos

Naturia Spiderfang, Naturia Pineapple, Naturia Ladybug, Naturia Oak
Naturia Oak
This card was notable as a potential summon off Isolde to make Naturia Beast because of its low level and EARTH Attribute (and its lack of a reprint, even to this day)

In the anime, this monster was a normal monster. In the physical game, it's better known by its retrain, which is infamous for helping enable the most powerful deck of all time.

One of the best single-use traps of all time, released in 2004, this card has only been played in the anime once, in GX, by Sartorious's lawyer.
