There are some major problems here.
1. Jinzo doesn't belong in an Oppression deck. That is just you not thinking things out I think.
2. Oppression doesn't do well in KCVDS. KCVDS has 1 of the slowest metas ever and you might see an average decks special summon 2 or 3 times per game max. With all the stun and Gadget decks floating around as the meta who do no special summoning at all save for monster reborn and chaos sorcerer you are gonna be looking at several situations where those 3 copies of Oppression become completely dead draws. In KCVDS Oppression is a side deck card, not a card that should be mained.
