Best ability/effect/card

[Mattao19]

What's the coolest ability/effect/card in the history of Magic? I don't care about power/toughness, instant vs. sorcery, or even cmc. Even if it costs 20 mana what in your opinions is the coolest/ most bad*** ability/effect/card you've seen?

I personally love the ability of  {Stuffy Doll} (I know it won't be the best (or even close) but I just love the whole design of that card!!

{sensei's divining top} is a stupid good card along with {æther vial}. As soon as I saw both of them first come out, I knew they had HUGE playing potential. Best part is æther vial wasn't even rare at the time!
