In my deck for Omnath I include command beacon because it’s a good way to get Omnath back into my hand. Plus if I have someway to play lands from my graveyard then I can always get Omnath back and play him for 7 mana
I'm personally a fan of Perilous Forays. Obviously not free (would be broken otherwise) but paying 1 mana for a lightning bolt while also getting other landfall triggers is pretty neat, including Warstorm Surge and the like as well. The CMC is a bit high, but I still think Omnath can handle that with this amount of ramp.
I have him he is my first and current commander I name it the fury of the kool aid man it's on Archidekt.com this is awesome price of glory and ancient Greenwarden.
Hi, I do this for EVERYONE! Patrons of a certain level get to work directly with me and skip the queue, but anyone is welcome to submit a deck. Just understand that you'll have to wait your turn to see YOUR deck in a video
