This card revived the entire pendulum mechanic at the start of MR 4. In the words of a certain someone - "Stick to the gameplan"
Heavymetalfoes Electrumite
Tearlaments Kitkallos
1 "Tearlaments" monster + 1 Aqua monster
This angry link monster really doesn't like trap cards. And for some reason its an @Ignister support card?

Volcanic
Avram
World Chalice, Mekk-Knight, Crusadia
This furry friend used to search a powerful archetypal boss monster. Nowdays the best search target is another copy of itself.

This link 5 accounts for 2 negates on an average Mathmech board. It can also function as an extender if you are missing a body. Make sure not to attack it with Fenrir though!
Firewall Dragon Darkfluid - Neo Tempest Terahertz
The Neo Spacian Archetype was designed by Jaden, but what happened to them to make them real
They were sent to space
Aleister

This powerful winged beast was widely used by many pendulum decks during the dawn of MR3. Although it is not a pendulum monster, its ability to return to hand lends itself to have good synergy with pendulum summoning.
Destiny HERO - Destroyer Phoenix Enforcer
1 Level 6 or higher "HERO" monster + 1 "Destiny HERO" monster
It's an average level 3 Cybserse-type extender. But at least its a cute anime girl.

This cyberse serpent saw little plan in Salamngreat as a way to out boss monsters they normally struggle to out such as Winda.
