What format do you want this U/G control deck in? Duel or multiplayer, Type 1,2, or casual?
Answering the above two questions in any deck-related question you post allows those willing to provide advice to actually help you. You must keep in mind that given the nature of this site, type 2 duelling decks are not exactly what many people play or even concentrate on here at the CPA.
To answer your initial question, though, either poke around on the net for decks called Con-Troll, or try the abomination I used to play, involving Iceberg, Hurricane, and Cerulean Wyvern. It didn't win much, but it sure was fun!
