Everyone likes really big creatures. This is especially true for us; well, at least for me. Most fatties used in legacy are creatures that can end a game on the spot and by themselves. Most of them are also relatively inexpensive. It is for this reason that many of the budget combo decks you will be introduced to will focus on resolving these fat creatures in different ways. Polymorph is a cheap mono-colored deck that was made possible (at least in mono color) by the release of the living weapons in the New Phyrexia set. Use either the living weapon Flayer Husk or the land/creature produced by Mishra's Factory or Wind Zendikon as an outlet to Polymorph or its stick version Proteus Staff. Since Emrakul, the Aeons Torn is the only creature in the deck you can congratulate yourself as you play the flying spaghetti monster for a measly three or four mana.

While it would knock the price up a bit, you always have the option to splash another color. The deck can easily splash white or black for additional protection and token producers like Beckon Apparition, Raise the Alarm, or Lab Rats. Chrome Mox can also be added for additional mana acceleration while Silence or Duress can be added as protection.
