I don't know why your not using Simic Growth Chamber it grants mana potential in the long game as long as you don't mind taking the tempo hit which your deck doesn't seem to do much early anyways. Also you don't run that many Artifacts or Enchantments so Bane of Progress seems good makes a big guy and disrupts opponents a lot. Also similarly Trygon Predator is a good Simic card. You have lots draw potential you might want to have more ramping effects Search for Tomorrow is a good one and if you want to go big Boundless Realms is another.

Yeah, I haven't gotten around to dealing with finding nonbasic land, other than what I happened to have.. will definitely pick that one up.

Boundless and trygon I had recently pulled off my maybe list. I will reconsider. I like boundless a lot but not sure what I'd pull out for it.

As for the things to take out I think maybe Roar of Challenge because doesn't seem to be good at protecting your creature as it is a sorcery and if your need unblocked attackers seems like more work then sleep and you have lots of remove as is. Also Reviving Melody seems bad its a sorcery, you have very few enchantments and there is simply better uses for grave returning spells. Also Devastation Tide seems less worse then Evacuation due to Sorcery versus Instant.

You might like Lorescale Coatl . Its like Chasm Skulker except a little worse.

Thanks arowdok those are very helpful catches.

And IATEAREPUBLICAN I just took out lorescale. It could make it back in at some point but probably not soon.

Oh haha my bad then

Vorel of the Hull Clade ???

Yeah, I have thought about that a couple times. I need to count up the cards it would synergize with to see if it's worth a spot.

I dunno if I see the point of lab maniac in this deck, which might seem weird because you do have a lot of Maro type cards in here. having looked at your list, you look like you have about 6, maybe 7 consistent extra draw engines going for you. that's not bad, but I feel if you're going to have both Maros as beatsticks and Lab maniac as an alt win con, you should find more ways to embolden both strategies.

Kami of the Crescent Moon, Mind Unbound, Lunar Mystic, Dictate of Kruphix, or better yet, Bident of Thassa and Coastal Piracy. Those last two will work like crazy because they not only encourage aggression, but they reward it as well.

rhystic study and mystic remora may work as well, as it not only gives you cards when your opponent casts a spell, but if they choose for it not to happen, it forces them to use mana, meaning they're putting themselves at a disadvantage either way.

Regardless of whether you make these changes or not, the deck is still rather impressive and looks fun to play. It's also fun to see the differences each player makes for the same color combo in EDH. to see what I'm talking about, you can check out my Vorel Deck, Biohazard, and see how I interpreted Simic silliness.

Best of luck and keep having fun.

laboratory maniac is cool, and works. I play a zegana deck a bit more dedicated to him, but with this build he can draw out on just 2 or 3 zegana plays, which makes zegana a more difficult to deal with threat. generally, not having the maniac means there could be a point when zegana dies and replaying her isn't an option because deck size. with him in the deck, people have to be even more wary than before of killing her, because you just win off of the draw out. so if she's in as a big creature it leaves people with more difficult than normal combat situations.

I like Rhystic Study as an option though, it does awesome things.

Yeah Rhystic Study is great but I've noticed it getting me extra hate. My usual table get very annoyed very quickly at "did you pay extra?"

Enter the Infinite ?

Enter the Infinite is just too cheesy for me I think. Besides, I'd need not only to be mana flush to cast it, but would need to make room for more counterspells to feel safe about it.

Really I think the only changes I'm likely to make at this point are to increase speed, after getting creamed by My girlfriend beat us all recently.

I think I'm going to remove a couple 6- & 7- drops to add some more low cost ramp like Cultivate and Kodama's Reach .

i love it......simply love it +1 for sure

Lol thanks! It sure is a lot of fun to play.
