Have you considered Giant Growth?

SlimJim83 Thanks for the advice. As I wrote in the description Aspect of Hydra is a better Giant Growth in almost every case, if you mean to add more pump spells I'll surely add Blossoming Defense, losing +1/+1 for hexproof definitely worth it.

They're a great point. Hexproof is totally worth it.

Greenbelt Rampager is a good card, but I dont think it fits as well in this deck. If you had more with energy it could have a lot more value.

HEX. Thanks for contributing. Greenbelt Rampager is less solid than the rest of the deck but the point is not to play it for 1 but to have multiple ETB effect for Experiment One, revolt for Narnam Renegade and curve fix using the extra 1 mana. I'm still testing this list so maybe I'll remove it however for now it's working fine

Tezzeret's Gambit?

Got it, yea that is good then because it is free counters.

lagotripha Thank you. Card draw is something this deck is missing, but probably because there are not cards good enough to deserve a slot. I would see Tezzeret's Gambit in a Hardened Scales build, where proliferate can be more powerful, this deck it's not focused on +1/+1 counters even if there are creatures that use them.

I get that, its just that you've swapped the Kalonian Tusker and a from the netdeck for some dismember and counter-using creatures in the lower slots, which plays to the card's strengths- the problem with the 1 drop increases is that while they're great cards, you're hardly running the haste enablement of 8-whack, and with the loss of devotion the original simply performs better- Scavenging ooze is a great card maindeck but it isn't enough to make up for the loss of synergy the deck faces in its most key cards- the ones that care about those (G)(G) costs. Narnam Renegade is just a 1/2 deathtouch when you play it.

Now if you were cutting the curve a little more for the aether revolt Maulfist Revolutionary or planning some ramp with Rishkar, Peema Renegade/Dwynen's Elite/Collected Company/Asceticism that could also work, or running Inspiring Call as draw and protection it might pull through, but as minor tweaks it waters things down in a way that doesn't help the overall goal compared to the netdeck- the playstyle that defeats the netdeck won't be any worse against this, and the changes you've suggested don't make space for the kind of unexpected plays that win games.

But if all you're looking for is a minor tweak, consider Lifecrafter's Bestiary maindeck- It'll draw some more cards and keep the beatdown going after the end is expected, and combined with a couple more dismember or Prey Upon it'll extend your range above more aggressive decks. Good luck, hope the brewing goes well.

Stompy is how I got into Modern also. It's a fun deck.

IMHO, you don't want Narnam Renegade:

1. There are only 2 cards in your deck that let you trigger Revolt voluntarily.

2. With Aspect of Hydra you are sometimes going to want to play Narnam Renegade pre-combat to get your Devotion count up so even your opponent's removal spells (usually cast during combat) won't always trigger it.

I think Attune with Aether might be interesting. It gets you the you need to make Greenbelt Rampager stick on turn 2 for , and drawing an extra Forest has some synergy with Dungrove Elder.

Other creatures worth considering:

Garruk's Companion: I play it instead of Kalonian Tusker because Trample makes Aspect of Hydra that much more deadly.

Surrak, the Hunt Caller: Unless your board is empty, he will usually be able to give himself Haste. He closes out games out of nowhere because no one ever suspects him.

Other spells worth considering:

Beast Within: Main-board answer for problem cards like Ensnaring Bridge, Liliana of the Veil, Ghostly Prison, Urza's Tower, etc. You can also destroy your own Forest on your opponent's end step for a surprise 3/3 attacker!

Heroic Intervention: Because board-sweepers suck.
