I've been wanting to put it in, but what would I take out for it?

Essence Harvest ?

Again, what would I take out for it?

this might be going out on a limb, but perhaps u could try replacing the increasing savageries for 2 essence harvest just to try it out and see how u like it. But i cannot say do it b/c increasing savagery is perfect in this deck. Just an idea hell dude your deck might be perfect the way it is im just throwing that out there. I like it alot.

I have been play testing this deck of yours, and i must say im very impressed with how quickly these guys get big i have been getting turn 5-6 wins on the playtester. i say that's impressive with it being a standard deck and how the mechanics engage. had a lotleth troll growing to an 18/15 creature on turn 5 and the slimes make great attackers/defenders for what ever you need them to be b/c of their indestructible ability. early game used the slithersheads in conjuction with the trolls and great early game dmg. Don't change anything man it's perfect in my opinion, dont fix what aint broke. I know ppl been telling you to add in the howlpacks but you already know they protect you from burn/creature removal and add alil dmg in.

Correction on post #22 the RANGERS GUILE protects your monsters from burn/removal

You have Rancor , you don't quite need Essence Harvest . If your FNM store does two head giant, it would be helpful so you could attack once then harvest again.

Thank you for the feedback! I'm planning on taking this to FNM tomorrow so I'll let you all know how it goes.

Gravecrawler goes well with Lotleth Troll but gravecarawler is kind of expensice but if you have the money you should replace Slitherhead for Gravecrawler
