Did my best to recreate my friends' old Ghave, Guru of Spores Abzan Stax EDH / Commander Deck that I had difficulty beating at one point. Unfortunately he didn't have a deck list available so I tried to remember what he ran at the time before he quit Magic: The Gathering entirely. The deck was designed to lock your opponents from playing ANY cards from hand and graveyard with no lands to tap mana for as well as no creatures on the battlefield. Basically animate your opponents lands into creatures with Natural Affinity and Nature's Revolt while Elesh Norn, Grand Cenobite makes them -2/-2 land creatures sending them to the graveyard.

Unfortunately the mana curve was REALLY high as it wouldn't of been able to keep pace with most Commander decks nowadays even more so in cEDH. So I had to make A LOT of cuts to the original build for a new build with a MUCH lower mana curve. The more Stax pieces I kept in the harder it was to put in cards that help synergize with other cards in the deck not to mention that I had to run cards that took up space for other cards that prevented me from losing my own lands due to state based actions like adding +1/+1 counters on my land creatures for example. More Mana Rocks could be run to counteract this problem or just allow my lands to be blown up to utilize my Saprolings as mana dorks with the risk of a board wipe losing me the game.

Ashnod's Altar should probably be in here.
Bastion of Remembrance or The Meathook Massacre combo with your commander.

I actually did manage to find some solid cards to bounce The Meathook Massacre as well as Oath of Ajani back to hand to recast later via Light the Way and Kor Skyfisher / Whitemane Lion. The idea is to cast The Meathook Massacre by paying 2 for X to give my opponents creatures -2/-2 with Nature's Revolt active or casting Natural Affinity with "Anthem" effects like Oath of Ajani and Mazirek, Kraul Death Priest pumping my land creatures' power and toughness. Rite of Harmony also synergizes nicely with The Meathook Massacre and Oath of Ajani for some extra card advantage as well and it has Flashback. I might swap Moonsilver Key for Mirror Box though. As for Bastion of Remembrance I was never really a huge fan of it however it does have potential with cards like Trudge Garden which goes infinite with Ashnod's Altar. It also has synergy with Blood Pet and Enduring Renewal. Leonin Relic-Warder does also combo off of Bastion of Remembrance with either Animate Dead, Dance of the Dead, or Necromancy. I would probably also need to run Felidar Guardian and Oblivion Ring for more blink effects. I have been looking into some combat damage prevention tools like Spore Frog, Kami of False Hope, and No Mercy. Pitiless Plunderer and other Treasure support might seem good though I may reconsider. I appreciate the feedback. I feel as though the mana curve might need to be lowered a bit more.
