Decided to play an elemental edh finally after mulling this over. Went with a pretty devoted control and destruction package since Horde of Notions can bring critters back. I also chose the cycle for elemental incarnations and Forces because they have some great abilities to play with in multiplayer. Vigor, Guile, Hostility, and Purity all have corresponding cards that use their second abilities, too. Comments are welcome, as are suggested substitutions.
With the high curve, I'd recommend 40 mana sources unless you are able to add more sources of ramp.
So...there's some ideas for you. I certainly don't mean to stomp on your deck idea. To be honest, one of my first Hordes deck looked very similar to what you currently have posted. There's nothing wrong with that...just that it won't be all that competitive in the average meta. If you're going for 'fun' points, you scored 10/10 imo, cause I love the elemental cycles that are available.
OK, after a bunch of changes today, I like the direction now. More elementals in the 5 and 6 range, less in the 7 and 8 range, making the ramp more effective. More functionality, too. Many thanks to GFireflyE, the suggestions added a lot of coolness to the deck list and definitely added fun. Very much in line with my philosophy. This is a casual deck, so I'm passing up a bunch of stuff that will make it competitive, but I like what I've added for sure. If you have some more fun suggestions beyond this, please send them my way. Thanks.
So I settled on the list below, I have it assembled, and I’m already noticing some trends. First, mana floods in fast with the ramp, reliably getting my bigs in ahead of curve. Horde of Notions is often the second creature in, meaning the color diversity is fine. Rite of Replication is a game breaker, already raping Magmatic Force, Celestial Force, Greenwarden of Murasa, Dread, and Fusion Elemental. I’ve seen the Vigor/Chain Reaction combo come up twice already. Torrent Elemental will win games, at least against my group. Earthquake/Hostility is godly, even more so when Purity is also out. Finally, Baleful Force and Cyclonic Rift are 100% deserving of the hype I’ve seen.
Can’t wait to test this on my friends, it’s going to be too fun and a half. Woot.
