You play a land followed by a
lion's eye diamond. You play
breakthrough for 1 mana and in response
sacrifice the diamond to add 3 blue mana. In order for this to work you must have at least one card with
dredge in your hand. You
dredge as many cards as you can and then play
deep analysis for its flashback cost with the mana gained from the diamond. Yet again
dredge as many cards as you can. By this time you must have at least 3 bridges in you GY (well you may be unfortunate sometimes...). If you still don't have the zealot in your GY,
dread return the
cephalid sage to continue the combo and then sac two zombies and the sage to bring the zealot into play if you find him, then attack and win. All these take place in the same turn, if you have the cards required.
If you don't have
breakthrough,
cephalid coliseum does almost the same work but with a turn
delay. If you don't have the diamond use
putrid imp.
