Hello everyone,

I'm looking for some feedback as I'm kinda stuck on what to change to get it more powerful. This deck is build around Lazav and the main idea is to mill/remove cards from the opponent hand and library in order to get Lazav more powerful and to get creatures that gets bigger based on the graveyards. As you can understand, decking out an opponent isn't my first strategy for winning but it can be done using the different cards on my deck. This deck will mainly be played against multiple opponents but I would think it can be used in a 1 on 1 scenario too.

Here's the decklist. All feedback welcome!

Yeah thanks for this, I've modified the topic title.

Comments are greatly appreciated!
