A Quick description of why every card is included:
Battle Fader : Ends the battle phase if you get attacked directly. Pairs well with skill drain, cause no pierce.
Swift Scarecrow : Does the same as Battle Fader only better, since it doesn't leave a body on the field.
Magic Hand : By far the worst card in the deck and only in here because of the hands theme. Replace with any other card if you don't need maximum hands.
Fire Hand : Destroys a monster on destruction and summons an Ice Hand . It needs something to destroy to summon though. NOT once per turn, so if their board is full and you got some life points crash, destroy monster, summon ice, crash, destroy spell/trap, summon fire, crash ...
Ice Hand : Destroys a spell/trap on destruction and summons a Fire Hand . It needs something to destroy to summon though. NOT once per turn, so if their board is full and you got some life points crash, destroy spell/trap, summon fire, crash, destroy monster, summon ice, crash ...
Prominence Hand : Probably the second worst card in the deck, but fairly useful to go into XYZs.
Thunder Hand : Basically a hand trap that triggers on a destruction of a Magic Hand , Fire Hand or Ice Hand and destroys something while summoning itself.
Lord of the Heavenly Prison : Protects your set cards. If you already have an Imperial Iron Wall going you can set anything and it won't get banished.
Pot of Avarice : Recycles your hands and draws stuff.
Pot of Extravagance : You don't really need your extra deck, draw stuff instead.
Pot of Prosperity :: You don't really need your extra deck, draw stuff instead.
Cauldron of the Old Man : Funnily a real problem for most decks here. Your main win condition.
Waboku : Dying is harder if you don't take battle damage.
Draining Shield : Quick heal, can be replaced.
Threatening Roar : You can't take battle damage if your opponent can't attack.
Rainbow Life : I have a soft spot for that card. It really isn't that good and the discard is kinda costly, but I just like that card for some reason. Can be replaced, since SR is kinda costly for what it actually does.
Imperial Iron Wall : Just a fun addition to be able to search anything with Lord of the Heavenly Prison , sadly deactivates 2 of the pots.
Except for the 2 Number 106: Giant Hand in the extra decks every monster is either a beatstick or a wall.
