Well I have decided to post the wind-up loop that is most commonly used in this format.

required for the loop:

The loop:
1)Normal summon Magician and special summon Shark.

2)Activate Magician to special another Magician from your deck.

3)Make Shark level 3 and use the other Magician to special a Rat from your deck in defense.

4)Overlay the 2 Magicians for Papolioperative.

5)Use its effect to turn Rat to attack mode.

6)Use Rat to revive the Magician that you detached from Papiloperative.

7)Overlay the Rat and Shark for Zenmaity.
