Deck looks great! Fairly similar to a Titania deck I have, myself (this one is probably built better, though!). I dunno if it was because it was a Brother's War commander card or if spoiler season fatigue is finally getting to me, but I hadn't even seen this card (the new non-meld Titania) until a few days ago... and then pulled one from my Brother's War box! Love how similar to the original card it is but also how it's different enough to warrant a slightly different playstyle at the same time. I think I still prefer the original one for the flavor-to-gameplay aspect of it but this new one is reeeaaaally interesting.

Thoughts on Nissa, Vital Force? Or the new Awaken the Woods? Also, odds of adding in the new meld Titania and her Argoth land?

@KBK7101 I was so incredibly hyped when this got leaked, I started building immediately. the new Titania meld Argoth, Sanctum of Nature + Titania, Voice of Gaea is interesting, but I'm not sure I would add the personally. I'm not leaning super hard into the mill part of Titania, Nature's Force's kit and the 2/2 bear isn't super enticing compared to the other ways I have of creating tokens. Unless I have some of the cards outlined above, it also removes a slot for a forest that can get triggers and be fetched out. Titania, Voice of Gaea  ^Meld I'm not considering, the 2 life on land graveyard isn't worth it imo, the only slot I can see swapping her into is Centaur Vinecrasher. Nissa, Vital Force was in my first iteration of my deck before some editing, and the only reason was because all of the planeswalkers are 5 CMC and one of them had to go. But she could easily swap in for one of them based on your preference, though I would personally swap her in for Nissa, Worldwaker. Awaken the Woods is a card I hadn't considered before just because I didn't realize that the tokens were actually forests. This changed so much with the card and makes it basically an auto include, I just need to figure out what I'm cutting for it.
