first off i am not the best deck builder but i do offer the best prices here at ODA.
so lets get started with the prices

Mecha Phantom Quasar: 100 OD
deck uses the mecha phantom beasts monsters to bring out quasar, deck is still not finished so i will pm you any changes i make after deck is purchased.

Burning knucklers (battlin' boxers): 225 OD
this is one of my favorite decks and is one of my best decks.

Black luster soldier: 100 OD
main card is BLS (the ritual one) focuses on spamming out level 8 (or even rank monsters. deck is inconsistent but is very powerful when opening with a good hand.

more decks coming soon.

custom decks:100-200 OD
varies by how much experience i have with the type of deck you want and how easy it will be to make.

Why does your deck shop end with "of death".
It sounds kinda scary :/ also there is nothing dead/undead in here

Why not name it jammy's little deck shop of horrors?

because of death sounds cooler and i'll have a zombie deck or 2 up here after i finish them.
also someone else already had of horrors in there shop name.
