One of my favored sets for an easy to assemble decently strong deck is fairy. The mere uncommon fairy witch card which brings forth more copies of just fairy fire just simply gets stronger and stronger the longer the match goes on. Then it's just simply a matter of making a small deck so that you can get back to your important cards as quickly as possible (the fairy witch, and whatever draw/healing cards you got set up to help make the deck viable). Self removing cards help stream line the deck and if you have troubles making the deck go down to no more than 10 cards you can always use gluttunous fairy to help remove the less useful cards permenantly (or just simply sacrifice fairy fires granted by the witches to gain 30 height even).
