Disclaimer: if I'm not mistaken this CAN actually happen. If not, feel free to leave me a comment explaining why it CAN'T happen (been quite busy due to work, so I didn't check all of the cards rulings). Thank you for your time.
Step 1: Greed must be activated.
Step 2: Activate Reverse Reuse. special summon 2 Morphing Jars face-up to your opponents side of the field.
Step 3: Activate Dirge Of The Lost Dragon and declare Morphing Jar (this card cannot be destroyed when your opponent controls a monster).
Step 4: Activate Book Of Eclipse, flip all monsters on the field face-down.
Step 5: During the end phase flip all face-down monsters your opponents controls face-up. Both Morphing Jars activate, then Dirge Of The Lost Dragon's effect applies twice, half your opponents life points 2 times, then they lose LP for each card drawn by Morphing Jar due to Greed.
Step 6: Win
