Hi, I'm new to the MTG scene and have been playing commander only on weekends. I know I'm considered a casual but I'm so sick and tired of losing to others, my pre-con deck just won't do it. I've always wanted to build a sliver deck what do you say is the power level of this deck. I want my vengeance

Hey there Tobuts! Honestly, I have a very hard time estimating the power level of this deck, because Slivers generates a ton of arch-enemy energy from the table, so I always 1v3 the group and typically lose. I can answer all your questions and provide advice to the best of my ability whenever you wish.

I want to build my own deck. I got someone who is selling me a basic sliver deck, want to know if it's worth it. Here's the link ( https://www.mtggoldfish.com/deck/3937172#paper ). At the moment I am investing in shock lands, fetch lands.

I think you could have a lot of fun with that deck, and it will be a nice experience upgrading it over time.
