What you guys think about 2 Bitterblossoms in the sideboard, I can see in the last few weeks that it's gaining popularity.

I am thinking of buying 2 for my sideboard but I am not 100% sure. I guess the main reason is beating Grixis Control?

It's the same with Liliana's Defeat, I think this is also mainly for Grixis Control.

It makes sense to create a good anti Grixis Control sideboard seeing the current meta, what do you guys think of this current development.

Thanks! :)
