Currently being tested: Willbreaker. I'm a bit skeptical of the card, as I fear it will end up either being win-more, or simply a colossal removal magnet. A friend insisted I put one in though. In testing, it's been promising. It replaced Spelltithe Enforcer, which was really only being run to fill the 5-drop Yisan and Birthing Pod chain spot.

I'd cut Mana Drain IMO. While its a good card, half your abilities make it impractical to cast. Plus running one counterspell seems too hit and miss. You may as well just include a card which is more useful in more circumstances.

A card which you could look into however is Seat of the Synod. While I'm typically not a fan of running artifact lands, it is both fetchable by Tez and can be untapped by him too, allowing you to pay for your Stasis indefinitely. And unlike your other mana rocks, it doesn't need any special conditions to play.

I dont like Jin Gitaxias in this build. at that kind of mana, you should just be winning the game and while the lockdown is nice, Craterhoof Behemoth just feels better.

Mana drain is absolutely worth running. It both shuts down a threatening spell and allows for explosive plays the following turn. It's a powerhouse in the early game, and rarely an unwelcome sight at any other point either.

I have too much artifact hate for Seat of the Synod to be beneficial. Kataki, War's Wage, Null Rod, and Stony Silence all hit it hard. It also dies to the many other incidental artifact hate spells. Tezzeret is currently under performing, so putting in a card that's otherwise bad that had synergy with him isn't a great idea. Since he's the only card in the deck with good synergy with artifacts, Seat would be almost strictly worse than a basic land.

Jin-Gitaxias is almost never hard-cast. He's an out to Fauna Shaman/Survival of the Fittest. Pitching him to grab Loyal Retainers is the normal strategy. He typically wins the following turn.

Craterhoof Behemoth is not good in Derevi. The deck wins through preventing opponents from interacting with the game and either forcing scoops via unbreakable locks or grinding out life totals. Swinging a few big beaters once isn't necessary. It's a win-more card in the deck. It also has no impact on a small board, unlike Jin, who can cause a colossal tempo swing by himself.

Thanks for the input though!

That's fair then. If Tez is underperforming, have you considered the new Sigarda, Heron's Grace? She provides a flying beater as a means of turning graveyarded cards into extra value. She also is another 5 drop. Not sure how she'd go, but worth a mention.

How fun is this deck to play? Your decks are very smartly built. I like the description, and responses to suggestions. I built a Tron version of Derevi, and I was hoping you could take a look at it. The Armored Bird. If not it's all good. Keep building, man.

Hey man, love the deck list. Sucks that Prophet was banned! What are you using to trigger Willbreaker? The only options that really stand out are Sakashima, Quirion and Derevi actives, which I would think would be better served for some other purpose. Doesn't seem like you can make much use out of him, unless there's something I didn't see.

I utilize Derevi's tap/untap ability to grab key creatures with Willbreaker. It diverts resources from locking down lands and untapping my own permanents, true, but it's well worth the trade off depending on what's on the field.

Depending on how many creatures I have on the field prior to casting Breaker, I can easily snag upwards of five creatures in a single turn.

Your alter game is on point. 10/10 would steal your alters for proxies again.

Thanks!!!
