Notes & Combos

Pot of prosperity is better than extravagance in the deck for several reasons.

1. its not forced to be used at the start of MP1 which allows for more flexiblity.
2. the ability to choose which extra deck monsters to banish allows you to avoid running unnecessary duplicates and put in tech cards. extravagance also has the risk of banishing multiple hexstias which severely hurts the deck.
3. being able to excavate 6 cards deep is usually more useful than blind drawing 2, especially with a deck like geists where getting faker is important.

Solemn warning hits most things that you want to use Solemn Strike on, but it also has the benefit of negating tri-brigade revolt, fusion destiny, etc.

Haunted rock is decried by many altergeist players for it being a subpar turn 1 play. However, its true strength isn't in its turn 1 plays, but for plays on turn 3 and onward. with haunted rock, the memorygant OTK described in rain's guide ( https://www.masterduelmeta.com/articles/guides/altergeist-guide-rain ) has its requirements lowered from 3 monsters on field to a 2 card one (which is pretty much any hand with faker), and dramatically shifts the playstyle to a midrange/control hybrid deck, where you shut down the opponents plays on turn 2 then finish them off on turn 3 to prevent them from topdecking any blowout cards like lightning storm.
