Cold Tiara
Dracotail
A wicked wooden spirit that has burned out. The barbecue grilled with this charcoal is so awesome that everybody thinks it's priceless.
Charcoal Inpachi
Vivid Tail, Small Scuffle, S-Force Chase
I:P Masquerena
Before the Mermaid ban, this 7-star brick was a cornerstone of the infamous 'Full Orcust Combo', bridging any 2 monsters with different names into a fearsome board.
Orcust Knightmare
A Quick-Play Trap that hits high-level monsters both on the field and in the Graveyard.
Called by the Grave of the Super-Ancient Organism
Dance Hash
Hecahands
This recent addition to Campbell's cube debuted in Age of Overlord, but was mostly overshadowed by an early excision from Campbell's cube.
T.G. Rocket Salamander
Realm Resonance, Loka Samsara, A Shattered, Colorless Realm
Visas Starfrost
Some early Sky Striker pilots experimented with a package that put 3 Spell Cards in their Graveyard and also searched this - the least bad 2nd target. At least it was a free summon...?
Toon Cyber Dragon
A Level 10 WATER Synchro that returns itself to the Extra Deck, upside-down, if you're on stream.
Artifact Lancea, Ancestral Dragon of the Ice Mountain
Mind Fetish
Fiendsmith
This tropical Tuner made an appearance in a few OCG Tearlaments lists, though probably not for its ability to halve something's ATK & DEF.
Fengli the Soldrapom
Draw of Fate, Primal Seed, Super Soldier Rebirth
Black Luster Soldier
This bizarre "fusion" spell can use up to one card from your deck, but it's a far cry from Rahu Dracotail - the "materials" it banishes are two Field Spells.
Ursarctic Drytron
A play pattern in which you add an "Evolution Pill" Spell, then link the searcher off to turn an opponent's monster into a Spell.
Relinquished Animadorned Archosaur
Chad Floors
Solfachord
The unique ruleset of the Genesys format gives this Cyberse monster an odd synergy with Vanquish Soul. What if Upstart Goblin could be revealed with Jiaolong?
Link Apple
Memory of an Adversary, Absolute End, Penalty Game!
Invader of Darkness
Despite its powerful ATK-boosting, multi-attacking & floating effects, this level 8 Synchro monster has only really seen play in Centur-Ion, perhaps due to its specific material requirements.
Chaos Archfiend
A Normal Link Tuner whose piercing damage refreshes your hopes and dreams.
Galaxy SerPentestag
Scary Battles
Crystal Beast
If you don't open Magicians' Souls, you might still be able to fuse into this archetypal Thousand-Eyes-Restrict-like.
Fullmetalfoes Alkahest
Treasure Panda, Man-Thro' Tro', Wattcancel (OCG ver.)
Ojama Yellow
The punctuation in 'World Legacy - "World Chalice"' disqualifies it from this category, but that doesn't stop it from being a search target for this Trap Monster.
Crusadia Krawler
Back in 2003, this monster had a very easy time triggering its handrip effect - because it could attack directly!
