Yahenni's Expertise Discussion

Firebones675 Baral have disynergy wit Metallurgic Summonings in the sense he not make a token. I would test it but i think if he is not on the board on turn 2, he don't make anything in a late game. Also he died if you cast Yahenni's Expertise it's sad :(.

Thanks!

I really like Fall of the Titans because if I surge it out off something like a Shock I can get one damage for every mana I tap straight to their face which can be game ending in a pinger deck, wheras Battle at the Bridge is better for catching up to an aggro deck. I am considering cutting the chandras, mostly because its not great to drop it on turn four without a solid defense though if I can untap with her up I feel like she'll do more than Yahenni's Expertise in terms of winning the game. I've been doing a lot of practice hands and with all the extra draws and scrys and low curve I'm not 100% sure i need many more lands. My curve is topping at Baral's Expertise (which is only in for the amazing Fevered Visions synergy and im considering cutting without that many relevant 4 drops besides chandra.)

Thanks for the comment on my deck. A few notes:

TheGodofNight on Metallurgic Artistry

No problem, I enjoy testing decks, although the control mirror was very tedious as both of us would have removal, but nothing to remove, lol.

Now as to the 3-3 or 4-2 split, the primary difference between your build and mine is that Saheeli's Artistry becomes copies 4 & 5 of Torrential Gearhulk (to quantify, this is against non control decks, as a counter spell can shut that down quickly). I went with an even split, to diversify my answers, because when I ran only 2 Metallurgic Summonings, it seemed that 85% of the time or more, both copies were on the bottom of the library, right next to each other (to be fair, that's just RNG, but I liked having the 3rd copy so I wasn't as butt hurt about losing one to removal or counters).

In your build, mainboard, you are hoping to win on one of eight cards (or a combination thereof), which is 4 Torrential Gearhulk, 2 Dynavolt Tower, and 2 Chandra, Torch of Defiance. In my build, I'm banking on one out of eleven win cons, 3 Tezzeret the Schemer, 3 Torrential Gearhulk (I'm only counting the 3 actual copies, not the ones that could be made by Saheeli's Artistry), 3 Metallurgic Summonings, and 2 Westvale Abbey  Flip (more specifically, the transformation Ormendahl, Profane Prince  Flip), and to be fair, in non control match ups, I have been able to use this as a win condition. So, I feel as though your build is a little more streamline, but in the mirror match, you might compete for answers if you go into a super long game.

As for Yahenni's Expertise vs Radiant Flames, this is really a flavor/Meta call. Your commitment to double swamp for Yahenni's Expertise is 8 lands (not counting Aether Hub as it isn't consistent swamp mana), whereas in my build, I am at 9 swamps. I find that I would rather have access to 3 colors more often, and in my build I can get there very easily, whereas in your build, sometimes that double black wasn't easy to hit all the time. The other side of the coin is this, if you cast Yahenni's Expertise and you don't take advantage of the free cast on it, it's just a 4 mana sweeper effect, whereas Radiant Flames is just a 3 mana sweeper effect. I get that the Expertise gets around indestructible, however this becomes more of a Meta question. If Selfless Spirits and Archangel Avacyn  Flips are dominating your Meta, then the Expertise might be the better call. Although, both of our decks are running enough removal, that I don't see a lot of decks able to flood the board fast enough to be a serious threat. To that end, I find that Grasp of Darkness fills the role of spot removal for most indestructible threats.

My biggest take away from the playtesting was that I could easily cut Harnessed Lightning as a removal spell for my deck and replace it with a 4th Grasp of Darkness and 2 main board Negate, or 2 Void Shatter, or anything like that. Harnessed Lightning really is only effective post board for me, but for you, it helps juice up Dynavolt Tower. The mirror is probably the best test for our decks as it helps you figure out what your long term strategy is. Against aggro decks, I think both of these decks would crush most of them with ease (of course, Aggro decks can get up underneath of a control deck, so they present a big challenge in some respect).

Again, if I were to refine Grixis down, I think that that U/B list I posted previously would be the ideal build, maybe with a few tweaks, but it does streamline what the Grixis deck does, except both of our decks have a lot more flare and personality in comparison. To our credit, we could easily streamline the decks to win, but then they become cookie cutter win con shells that don't represent us as players or individuals. The obvious improvement inclusions would be Liliana, the Last Hope (this gets back our gear hulks, so double value there), Kalitas, Traitor of Ghet is a fantastic companion to a suite of removal spells, as he makes zombies and exiles an opponent's creatures, Transgress the Mind should be a main board "silver bullet" as it takes out a lot of the win conditions that folks are running and the removal/counters takes out the rest, and lastly, Jace, Unraveler of Secrets/Ob Nixilis Reignited are just fantastic cards that can give you advantage, spot removal, or inevitability. Control is poised to be powerful, and I think we are on the cusp with our decks. Thanks for all the input, I'd love to hear any other thoughts or ideas you might have.

geoffrey Thanks for the up-vote and great input and enthusiasm! It recovers decently well after board wipe because of Reckless Bushwhacker's surge and Gideon's and Nissa's pooping out tokens lol. basically everything is a token gen and the thing is you never want to go too wide with it so you don't really fall victim to board wipes unless you know you can save yourself with a heroic intervention in hand with mana up after side boarding but other than that you just have to not go too wide against heavy removal matchups. Also you generate counters quickly so if someone tries to Yahenni's Expertise you your creatures are high enough toughness they don't fall victim to it or if they do hopefully you didnt go too wide. As for Chandra I haven't thought about it too much but I may have to try it out. right now for grindy games I have Tireless Tracker sideboard and sufficient removal. This deck is still in the works so keep checking back! I'm grinding all day everyday to make this as clean as it can be! Hope You enjoy it!

the +1 toughness really helps protect my creatures though, equipping it  Flip to an Inventor's Apprentice or Stone Haven Outfitter takes them outside of Radiant Flames/Yahenni's Expertise/vanilla Harnessed Lightning range. This is quite important since all of those are cards are played quite often and especially the sweepers are dangerous if they would be able to completely wipe the board.

Thraben Inspector could definitely be good in here. i'm currently trying out Bomat Courier and seeing how that one does, they kinda fill the same spot.

Occultist,

Man, I like your ideas, but if I add all these other things (card draw, creature protection, graveyard return), then there is no focus to the deck. I would have to take out some discard and removal spells to make room, and I'm not so sure that would work. What are your ideas on how to change things?

My side deck definitely needs work. Before Aether Revolt, I only had Flaying Tendrils. Yahenni's Expertise is supposed to replace it. Tree of Perdition was an experiment. I thought it'd be fun to switch things up, but it does not fit. I agree.
