Looks pretty decent compared to a lot of other superfriends decks I've seen that are just "include all of the planeswalkers I can". As you said in the deck advertisement, Karn, Scion of Urza really would be a good fit for this deck, especially in comparison to Tezzeret the Schemer, but I also acknowledge that it is an expensive option. My one other recommendation would be Settle the Score.

If I get Karn 40fy he's a sure bet because his dudes can get really big thanks to Tezz

This works well.

Make sure you play at a decent pace, or you won't win many matches 2-0.

Steadily enough that you don't waste time, but not so fast that you confuse your Opponent.

+1 from me.

Nice Showdown result.

Argy The big issue imho is going to be U/W control. I may have to slot in more enchantment removal to deal with the removal white is going to have

They can only have so many copies of Cast Out and Ixalan's Binding in their deck.

Personally, if I were you, I'd be running 4x Syncopate and 4x Negate, with the goal of running them out of their removal spells.

When I've been testing this the matches go for a long time.

Is that the reason that you're not getting many 2-0 scores?

Don't feel too bad about losing to a newbie.

They often have a surprising advantage because their decks aren't tuned to the meta, so they can surprise regular players.

I'm looking at my cards and I'm likely going to dump Tezz and Yawgmoth's Vile Offering. Tezz because he doesn't do much to the board and Yawgmoth's Vile Offering because it's a difficult cast with very little payoff; maybe add another counter or another land.

I have to change the decklist because I have made some recent changes to it that changes how the deck plays now

Yeah I agree that Tezzeret the Schemer and Yawgmoth's Vile Offering aren't doing much.
