This is my first writeup for a deck that I created. Any constructive criticism is welcomed and appreciated. This is not a finished deck and mostly thrown together with cards that I have. However, it's performed so well in the few games I played that I felt it needed some other players to look at it and make comments. 

Last season I played a lot of Bant Manipulation, I'm a green player at heart, so creating and using that much mana was exactly what I love about magic. When M20 was spoiled I was extremely interested in Elementals as a tribe. The more I saw people use and talk about Risen Reef over the last week the more excited I was to play the card. However, I didn't want to burn my rare and mythic wildcards on Chandras and Omnath until the meta settled a little and I knew the right ratios. I started thinking about how Risen Reef creates a bunch of mana, and I thought about my Bant Manipulation list. It's a lot of fun but I wanted to use the two copies of Finale of Devestation I'd got opening packs. 

I decided, why not use them together? Risen Reef creates the mana, nissa ramps it further, cast a big finale of devestation and suddenly the Risen Reef and all of the other small creatures I'd use to trigger Risen Reef become massive. Swing in for lethal on one turn. I started thinking about what creatures to grab with Finale. Rhonas was a choice but it hasn't performed as well as I'd like. It doubles after it comes in so the creatures don't get massively bigger before getting the +10/+10. So far I'm liking End-Raze Forerunner the Overrun-like effect is effective even on the leafkin druids and most importantly it gives everyone trample so it's even more likely to be lethal in one swing. Even if you only have 12 mana and Finale of Devestation, End-Raze Forerunner swings for 17 by itself, just a little early chip damage and you can come back from a board wipe. 

Now this deck does suffer against counter heavy decks, but there aren't a lot of those going around since little tef is so prevalent. Board wipes and removal are painful but you still get value from just playing your elementals. And removal they spend on a llanowar, risen reef, or cloudkin is one less they can use against nissa and her land/elementals. 

Ideally, I'd like to use two more Finale of Devestation because they deck is not great without drawing that. It would also be nice to Finale for 3 and get a Risen Reef if I'm not playing against removal and still be able to reliably draw into another Finale. I also think that just having more End-Raze Forerunners would be better. I'm also not super sold on Growth Spiral, it is a draw but after a Risen Reef hits the field you don't often have lands in hand to play with it. 

Again, any suggestions are welcome! Thanks for taking the time to look at my deck!
