Forum:WHICH MONSTERS, SPELLS AND TRAPS DO YOU THINK WORK GREAT IN ANY DECK?

I'd like you to list what you think to be the most versatile, incredibly awesome monster card, spell card and trap card; try to pick ones that work great in just about any deck. They shouldn't work only for a specific Type, attribute or arch-type; they should benefit the player no-matter what deck they're using. When I receive enough favorites, I'll assemble a deck using exclusively the cards found on this survey. Thanks for your help! Have fun posting! Monster: Marshmallon (can't be destroyed by battle, and deals out 1000 damage!) Spell: Lightning Vortex (Destroy all your opponents face-up monsters with a single discard!) Trap: Magic Cylinder (Negate an attack, and potentially deal a crap-load of damage!)
