Chaos Emperor & Yata-Garasu Lockdown

This is one of the most infamous Lockdowns ever played. It is also very simple.

Your basic requirements are:


 * Chaos Emperor Dragon - Envoy of the End
 * Yata-Garasu
 * Sangan or Witch of the Black Forest
 * Call of the Haunted or Premature Burial

How to play it
Call of the Haunted or Premature Burial should be played first. If Sangan/Witch of the Black Forest is already on the field before your turn started, skip this step.

Once your searcher is on your side of the field, Special Summon Chaos Emperor Dragon - Envoy of the End, then activate it's effect. Once your searcher goes to the Graveyard, search out Yata-Garasu from your Main Deck. Normal Summon it, and attack. If this were carried out near the beginning of the turn, it will require 40 attacks to reduce 8000 Life Points to 0.

Assumptions & Weaknesses
It is assumed that the player is either playing a video game, or is playing Traditional Format. In either case, it is also assumed that the relevant cards needed (i.e. those mentioned above) are used at no more than one.

Weaknesses of the Deck are numerous. At the time of the strategy's height, very little could stop it. However, with increasingly-centric play towards the Banished Zone, this is now an exploitable weakness. Chaos Emperor's summoning condition requires one DARK and one LIGHT monster in the Graveyard to Banish for the card to be Special Summoned to the field. If this cannot be satisfied, the strategy is dead in the water.

Yata-Garasu is also a weakness that can be exploited. If it is sent from the hand to the Graveyard (such as with, say, the effect of Spirit Reaper), it is very difficult to recover from that (Unless the player specifically structures part of the Deck to cover this potential eventuality).
