Those are the cards I would typically add to a deck as a skeleton.
I really like both Trishula and Mist Wurm, though to be honest, Mist Wurm has been a lot better to me than the former... Trishula never breaks the game for me, sadly.
And as much as I think Sangan is a nice guy, sometimes I don't think he fits. Nice guy, though :D
As for the list I was compiling, I'll add Trishula and Dark Bribe.
edit After some thought, I'll add Marshmallon, Spirit Reaper, D.D. Crow, Neo-Spacian Grand Mole, Fissure, Hammer Shot, Smashing Ground, Scapegoat, Swords of Revealing Light, Book of Moon, Raigeki Break, The Transmigration Prophecy, and Compulsory Evacuation Device.
