What're your best team combinations?

Just curious. What are your favorite Champion combinations that you've played as or wish to play as? This can be 2-5 Champs, any combination even if it's totally non-Meta. You can also list as many combinations as you want, as long as it's not totally random (as in, I'd like to see a reason why you like that combination other than "I just like it").

I have two favorites. Kalista ADC w/ Sion Support and Veigar Mid...so much CC it's not even funny. And there's also Draven ADC w/ Blitzcrank/Thresh Supp and Yasuo Mid, because the damage output of Draven and Yasuo together with the grabbing power of the Supports just makes for a great time.
