MTG Salvation

I'm doing pretty good, hopefully ur doing well. I'm running more glades over stomping grounds because I feel like they are most likely coming untapped without having to pay life with fetches. Stomping grounds I feel is a must for early game though that's y I went with 2. That's my biggest worry. I feel like carnage tyrant after rotation is going to be like 10 to 15 bucks as compared to 35 currently. Granted he is a huge beat stick

So I'm working on a deck list.. this is what I have worked up and would love any advice. This is the mainboard.

Land base
2x Stomping Ground
4x Cinder Glade
4x Valakut, the Molten Pinnicale
4x Wooded Foothills
2x Forest
9x Mountian

Creature
4x Primeval Titan
1x Reclamation Sage
4x Sakura-Tribe Elder

Artifact
2x Relic of Progenitus

Instant
3x Lightning Bolt

Sorcery
4x Search for Tomorrow
4x Farseek
4x Explore
3x Sweltering Suns
4x Scapeshift

As for the sideboard.

1x Carnage Tyrant
3x Obstine Baloth
1x Tireless Tracker
2x Damping Sphere
1x Relic of Progenitus
2x Anger of the Gods
2x Beast Within
2x Nature's Claim
1x Ancient Grudge

Also how much do u guys think Carnage Tyrant is going drop after rotation. I don't want to pick one up and regret it because it sunk like a rock

With deathrite being banned I am reworking my deck from top to bottom. I also going to drop from 4 natural order to 2, I just don't want to completely cut it out of the deck. I'm going to add lanowar elves, ezuri the rengade leader, and priest of titania to the deck. Pretty much switching from being green/black to mono green mainboard. I sadly still need to get cradles
