If weve gone down the hatebear route which I believe is optimal then a combination of ways to all-out attack and buff our creatures is optimal
It used to rot in my trade binder when I was your age, so take good care of it. The Water Crystal The Water Crystal wouldnt be my first choice for a win condition, but hey, if the format is actually slow enough you could maybe attempt it
Once you get back to Pioneer or Modern, Nature's Rhythm is competing directly with cards like Green Sun's Zenith, Chord of Calling and Finale of Devastation, which means you are going to need a specific reason to play it over the other powerful options
You'll need a lot of protection spells, though, because this commander will be a removal lightning rod
Either way, I think what we ended up with has been a solid list, and all of the cards on it are deserving of their spots
Expensive to cast, but thats why we play Commander, right
