1st set is done and actually functional as a 20 card deck.
Example situation of this deck:
We will assume our opponent went first with a set monster and a spell / trap card
In your hand: (WallRig), (NullP), (Tenpai), (Bulk), (Devil)
1) Activate Wall Rigging to place 3 cards on top of deck: wicked, dave or sunset (2000+ beaters) , devil (to pop monsters), cosmic(to pop back row)
2) Summon Null to draw cosmic and summon cosmic by tribute null to draw another majong monster and destroy the set spell/trap.
3) Summon Devil by tributing Cosmic, wallrig null and cosmic now in graveyard, to pop opponent monster. At this step our opponent now has nothing on their board, and we have devil on the field..
This is where we start establishing 1000+1000+2000+ ATK monsters for lethal. To do this we special summon Bulk and tribute it off for a 2000+ beater. Our board is now 3000+ Damage, in order to get the final 1000 Damage we use Tenpai to add a "Mahjong" from the grave and special a monster from our hand. For this you want to choose a "Mahjong" that will give you 4000 total ATK.
You now have 4000 Damage established vs an empty board so now just attack for lethal and O-T-K.

I will try to simplify the text next cause its a big TLDR.
