okay so I've been doing some long and deep thinking and I think I have my deck set up. my sideboard feels/seems solid through the playtests I've done. what I'm asking is if this was your deck.

how would you side against the top archetypes currently? like what would you remove/how many and what would you put in its place from the current sideboard as is.

I'm open to the idea of changes if these don't work out, but for now I'd like to keep board as
is.

please, your thoughts?

my friend was suggesting something like this..

Against Naya Blitz: Pillar
Against RDW: Volcanic Strength, Pillar
Against Jund Midrange: Volcanic Strength (for game 2
only), Traitorous Blood, Pyreheart Wolf
Against Junk Rites: Pillar, Traitorous Blood, Pyreheart
Wolf
Against Esper and Flash Control: Pyreheart Wolf
