Magic the gathering- what's your favorite creature for 1 mana or less?

I know this isnt the answer you're actually looking for but I would say the card dark depths. Free to play, has 10 ice counters on it, to remove a counter you must play three mana. When all counters are removed and you've payed 30 mana you get a 20/20 with flying thats indestructible. The thing is, in extended, I have created an infinite mana combination and can take it out and remove all counters on turn 4... HAHA
