MTG Salvation

I'm a real noob and still trying to figure out how to have the name of the card link, for some reason I'm doing something wrong. So I will edit this post once I figure it out. I've been gone a while and thought I'd copy someone's deck I enjoy until I realized it's for the wrong format I play >< I play 1v1 Traditional and not multiplayer. NGW's Competitive Lazav Control / Voltron deck is multiplayer focused and I understand those decks get wrecked in a 1v1 environment. If anyone could suggest cards in this list I should remove and what to replace them with to make it 1v1 competitive I would be very grateful. I've been away from Magic for far too long to use my own head and creativity to figure this out on my own. I've been on Edhrec and tappedout but it's too late now that I've already purchased 90% of the cards from this persons deck. Thanks.
