While creating a video about my first impressions on Modern Horizons, I ended up stumbling bass-ackwards into a fun and slightly crazy combo using [sc name=mouseover card=Wrenn and Six], a new Planeswalker revealed in Modern Horizons. In this article, I'll explain how the combo works, then give my list for this deck. Be warned, this list it not yet optimized. I do feel that it has a fair chance of doing well. The core combo revolves around Wrenn and Six's +1 ability to return up to one target land from our graveyard to our hand. We want to pair [sc name=mouseover card=Wrenn and Six] with [sc name=mouseover card=Crop Rotation] as our Signature Spell. [sc name=mouseover card=Crop Rotation] allows us to sacrifice a land in order to grab a land from our deck and put it on the battlefield. Sacrificing a land isn't a big deal, since we have Wrenn and Six to get it back. The ability to swap lands out for better lands will give us huge advantages against our opponents. We will want to take advantage of the London Mulligan in order to make sure we can play Wrenn and Six on turn two. Appropriately colored dual lands are ideal, but not a necessity. We are happy to have a fetch land in our opener as we can recur it with W&6. As long as we have a Forest and a Mountain by turn two, this combo is set. This looks innocent enough Once Wrenn and Six are on the battlefield, we use an open green mana to grab [sc name=mouseover card=Thespians Stage] with [sc name=mouseover card=crop rotation]. Play a second green mana source from our hand, or use Wrenn and Six to retrieve the one we sacrificed for Crop Rotation. We should now have an open green and red mana source as well as Thespian's Stage. Tap out to play Crop Rotation again, this time using it to grab [sc name=mouseover card=Dark Depths]. Since Crop Rotation is an instant, we can wait to do this at the end of our opponents' turn to help avoid land destruction, countermagic, or getting hated out of the game. But re
