Beast, Beast-Warrior, or Winged Beast
Gladiator Beast Bestiari
Winged Beast
This synchro... 12(?) monster is almost never used for non-FTK related reasons. Distant Coder, watch your back!
Phantasmal Lord Ultimitl Bishbaalkin
First released in 2008, these monsters were required to play any card with a white border
Tuner
What used to be a one card rank three, is now a one-card combo for a powerful deck... doesn't really help its brickiness however
Tour Guide from the Underworld
Judge! My opponent activated this spell card, and is saying I can't trigger My Friend OR Street?
Herald of the Abyss
Brigrand the Glory Dragon
Beast
This link five wouldn't be so teriffying... if it didn't take one of your own monsters with it
Underworld Goddess of the Closed World
This piece of legacy support has seen a ton of extensive play... just not by pegasus... I don't know if he knows what a link is
Anima
One of the many decks that end on a towers, we need only one of their cyberse monsters to make this category work... lets pick the red one!
Achichi @ignister
Judge! My opponent activated circular and sent sigma to the graveyard before I got a chance to respond! Why can't I ash it?

Tri-Brigade Arms Bucephalus II
Winged Beast
This powerful psychic used to be more common, but now, due to its limited applications, one is truly taken by surprise when it gets activated.
PSY-Framegear Gamma
This one word is the only thing keeping Dug the Assaulter from searching for "Upstart Goblin"
Rider
This vanilla may seem innocent but don't let that fool you, it forms an almost unbeatable combo. This rose certainly has a thorn!
Sunseed Genius Loci
Judge! I veilered their effect on field, just because the monster is attached to this extra deck monster, why does it still get to resolve?
Xyz
Fire King High Avatar Kirin
Beast
DAILY DOUBLE
More of a jumpscare in edison format, this flip monster is not threatening in and of itself... but the Raiko that follows is
The home of an archetype of fusion substitutes, also a place of black magic... or at least the magic cards are black.
Swamp
Because this machine was not given a once per turn, it would search sometimes five times for the opponing combo... only to be unplayable just one month later
Superheavy Samurai Soulpiercer
Judge! My opponent gave me this monster, I discarded a card, and now is saying I activated it! He doesn't get to thrust upon me!
Gen the Diamond Tiger
Dragoons of Draconia
Beast-Warrior
Maybe the best jumpscare in modern play, one monster can turn your opponents extension into ability prevention.
Super Starslayer TY-PHON - Sky Crisis
This spellcaster has been everywhere, she's a shaddoll, a gusto, a ritual beast tamer, and her sister is a charmer!
Winda
This edison staple is technically full Tri-Brigade combo, guess the negation doesn't really work on graveyard effects
Rescue Cat
Judge! My opponent activated evenly matched and is saying I have to keep this card! I'd much rather keep fateful adventurer!
