What are your thoughts on Scapeshift in Oathbreaker. The first game plan/deck idea I had for that would use Nissa, Worldwaker as your commander with Scapeshift of course. Ramp into a turn 3-4 Nissa, then untap four forests and cast Scapeshift, use Scapeshift to find Dark Depths and Thespian Stage. Pros for this game plan: you don’t have to give a fuck about Nissa after Scapeshift fires off, if try one fails you can still go for try 2 with out being low on mana since you’re already a mono green ramp deck, and a 20/20 flying indestructible is kinda hard to deal with in a 20 life format. Cons for this game plan: sorcery speed, kill one opponent at a time and it feels sad if someone plays control 🙁
Similar to Scapeshift, Crop Rotation could fill this role and probably is a straight upgrade in this format also allows more options for a commander, being Garruk Wildspeaker, Nissa, Worldwaker, and Nissa, Voice of Zendikar.
