The Goal of this deck is unclear BUT there is a lot of ways you can go about it.
Who knew all you needed was the best mill engine and every one-of.
Plans: Make Hydralander by milling with tear engine which is easily searchable via instant fusion or just finding a card that mills (Which there are a lot of)
Possible end boards: Grapha, Barone, Buster Dragon with blader and equipped welp, hydralander or eschatos which are free special summons as long as you can get them in your hand (Ptolemy M7 puts from field or grave into hand which in most situations your whole deck is in the grave), arrival (rare but funny and with buster dragon & blader can make barone then summon back buster dragon),
Pros: It's funny and since it runs off tear/ishizu fuel it's pretty easy to setup. The end boards vary but are endless in nature from graveyard disruptions, extra deck and on field floodgates, and funny hydralander mill popping for more fuel. Many cards can be changed out for others but as long as it promotes the mill. Tri-brigade engine helps hydralander orbit eff work which is bassically a pot of prosperity which can find any monster in your deck up to the amount of monsters in grave. You can run multiple of the same spell/trap for consistency since hydralander only needs different monsters.
Cons: D-shifter, necrovalley, abyss dweller, LITERALLY ANY GRAVEYARD NEGATE, ashable kitkalos, forbidden droplet, dark ruler. can go second to some degree but idk.
Conclusion- funny mill laser go brr
