This looks like fun. Funny that it's your Modern deck because to protect your main Mycoloth move I was going to recommend City of Solitude haha. I'm sure there is a modern equivalent. But yeah it's hard to know what to add in here since it looks like it's well tuned, and even harder to know what to cut!

I do love Elvish Visionary in here. Dual purpose for an already good and underrated card in my opinion.

All those cards look good - At this point I'd say it's ready for playtesting vs some common decks, and you can see where the vulnerabilities are - it's often difficult to know that before-hand. Obviously control is a problem but that's a problem for most decks and sometimes it can be cured by just drawing another of whatever they countered, and since you have so much mana ramp, if you trade 1-for-1 you will still come out on top once a spell sticks that they don't have a counterspell for. I would definitely keep some Guttural Response or something in the sideboard.

You might also want to put some Reach in there, as you have no flying defense. Or just put in a Hurricane if you need a finisher or Windstorm if you don't want to hurt yourself.

A Fog would allow you to swing with everything without worry.

The Windstorm would be amazing. Especially with Life and Limb out. I'll get tons of extra mana.

Now, I know I don't have flying or anything, unless I get Akroma's Memorial out. Then, everything is flying. But perhaps the Windstorm will be helpful in case I don't pull the Memorial in enough time. Also...Fog would be a wasted card. When I hit, my opponent is dead. Although...if THEY had a Fog, perhaps I'd get screwed.

Dammit, there's too many possibilities to try to account for. Gotta see if there's stuff I can take out to fit things in. Perhaps the Llanowar Elves. I dunno if I need quite THAT much of a mana ramp.

Jade Mage is good, but not as fast as your other cards...and yeah, that's a lot of mana elves. And even though it hurts you could cut a Craterhoof Behemoth since you won't need but one since it's like an Overrun...

Maybe some green removal - in the form of the "Fight" mechanic. Maybe since Mycoloth likes +1/+1 counters anyway, use Hunt the Weak or Mutant's Prey?

Or a good old fashioned Harmonize to speed up the card draw? That's always important when looking for combo pieces. And since your combo piece is a creature - maybe Primal Command? The alternate abilities could always help keep you alive or get rid of a pesky permanent that is stopping you...

Just discovered this card, might be fun in here: Fungal Sprouting

I looked at that one...I don't usually have very many high power creatures though. Originally, this deck was a Green White monstrosity with Seraph of the Masses, and THEN it woulda been awesome. But really, until the Mycoloth comes out, or I'm running with the Beastmaster Ascension popped, then it just doesn't make much sense. 4 mana for a single saproling? That's worse than the Jade Mage and it doesn't share the fact that the Jade Mage can do that multiple times a turn. (Which is why I don't mind the 3 mana activation. No tap needed)

I believe Primordial Hydra is one to keep in mind as well. It can also get completely out of control. Nice deck!

Nice suggestion. Put it in my Maybeboard. I'm thinking about moving out one of the Managorger Hydras, and one of the Servant of the Scales to make room for 2 Primordials. I'll test a bunch that way too.

If you want to know how to give your hydra haste you could play Exava, Rakdos Blood Witch if you splash for red. She gives haste your whole team.

RomanCenturionX: That's actually a great idea. I already have the Birds in the deck, so just splash Stomping Ground and maybe a Blood Crypt, and I should have enough to warrant it. I'll see if I can work that in. Thanks!
