white-blue can be fun,I once had a great lil W/B in which every card either healed or prevented damage,or dealt direct damage to my opponents creatures.only defeated once, a powergaming mate of mine built a deck SPECIFICALLY to counter it.good times.
I also enjoyed great success with a masques 'Rebel' white weenie deck,and there was also my green-red-black 'for the lulz' deck was great fun too
edit

oh,just remembered my favourite dick move (look up the cards if you don't know them) :
sylvan basilisk +
lure OR alluring scent
I'll not give away spoilers on this.suffice it to say,roughly mid game is the best time to do this,when you and your ertswhile opponent have a decent collection of creatures on the field.
