Forum:What are the 'must have' Trap & Spell Cards?

So, what do you consider as your must have trap or spell card? I'm just curious what people think. I'll throw out two cards I really like as an example:


 * Scrap-Iron Scarecrow - Great way to save your monsters!
 * Magic Cylinder - Another great way to save your monsters - AND inflict damage on your opponent.

Any others? And why do you like them? Kungfu-mama 22:32, 20 August 2009 (UTC)
