Vazi is amazing. She is the commander I have the best winrate with BY FAR. It really comes down to how you make deals. I am always saying: It's not group hug, and I will not be extorted into giving away treasures so that people don't attack me. But I am willing to pay another player to attack a specific player with specific creature or something along those lines. Getting some small but favourable deals really goes a long way of setting you up for success. My recommendations for includes are Wishclaw Talisman and Scheming Symmetry instead of cards like Gamble. If there is a threat then getting two cards to possibly deal with it is better than getting just one. Who cares if it's one of your opponents who gets the card? Let them be your pawns. Pay them to play their cards in a way that furthers your gameplan. Don't stop woth treasures. Everything is negotiable. Oh you think that enchantment there is shutting you down? Well let me get rid of it for you, but what can you do for me then? The golden rule is: Don't break deals. If others break your deals make them a public enemy by setting a bounty or something. If you lose because you made a bad deal then accept that but DONT BREAK A DEAL.
