Yahenni's Expertise Discussion

magicsheep on So Many Saprolings

3 days ago

I tried playtesting this deck a couple of times, here's my feedback.
1) The deck plays like a semi-typical midrange deck, as it does OK against both control and aggro but not excellent against either. At the moment, I would say that this deck is probably better against aggro than control, but that's my opinion. This is the sideboard I used:
3x Duress
2x Lifecrafter's Bestiary
2x Naturalize
1x Verdurous Gearhulk
1x Yahenni's Expertise
2x Blossoming Defense
1x Fatal Push
3x Cast Down
2) The deck severely lacks in removal. I found myself using Fatal Push and Cast Down in almost every sideboard match. However, once I got this engine running the Saprolings were able to overwhelm my opponent. Another card I would add is Blossoming Defense, which I used in the sideboard to protect my key cards. Frankly, I think the mainboard is very vulnerable to removal and burn spells.
3) This deck has a lot of synergy with Saprolings and once I'm able to get the cards working together properly and I'm able to protect them with Blossoming Defense, this deck plays extremely well.
This is a great first deck that is competitive and powerful. The theme and construction was great. Excellent job amorilinguae!

Hi really like your list really good for the money! for the main deck Greenbelt Rampager and Ridgescale Tusker could be good option I'm not a big fan of Implement of Ferocity I know it's sometime good but you can't afford the loss of tempo. For 2 mana this deck can do a lot. also Duress is in most case more usefull then Divest especially that you have 4 Putrefy if I were you i'll go more into the agro side of this deck dropping Walk the Plank for Blossoming Defense and maybe dropping 1 Duress and 1 Putrefy for 2 Attune with Aether if you feel you need a LOT of aditional card draw Lifecrafter's Bestiary

for the sideboard 2-3 Heroic Intervention. I know it's 5$ but against board wipe you have almost no hope to win. 3-4 Natural State are always a good sideboard option 1 Yahenni's Expertise is a little akward sometime but if all your creature are 4/4 it's a game changer Lost Legacy could be usefull for the rest you could put your copy of Divest

Changing it into a more controlling deck, keeping some of the main combo pieces but getting rid of some of them.

Animate Dead Mystic Remora - more of a multiplayer card then Highlander format. Rapid Hybridization - will be adding Fatal Push eventually. Reanimate - also more of multiplayer card as I don't play the many fat reanimate targets myself. Gilded Drake Dramatic Reversal Isochron Scepter - not playing enough mana rocks/dorks for this to be viable. Lim-Dul's Vault Arcane Denial Exploration - will add a Courser of Kruphix Swan Song Sword of Fire and Ice Batterskull Seedborn Muse - more of multiplayer card. Sensei's Divining Top Counterbalance

Heya AquaticAce26, thanks for the complements.

I think winter orb is bad; and also it does sort of the opposite of tabernacle. Tabernacle stops decks that use creatures for mana; winter orb rewards decks that use creatures for mana. For a tabernacle replacement I'd probably just run a board wipe; Yahenni's Expertise is possible, or just Wrath of God or Damnation. But if your meta doesn't have a lot of creature decks then you could just play something else more appropriate. If your meta is Sisay, Breya, and Kess, then only Sisay is really creature-based; you might just want to play another Rule of Law, or counterspell, or Imprisoned in the Moon if Sisay is the strongest of your opponents.

The best thing that Timetwister does in the deck is recur our enchantments; combo'ing with notion thief and being a strong turn-1 play are just nice extras. The next best actual wheel is Time Spiral, which is much cheaper in dollars. Although Days Undoing doesn't seem terrible. The next best recursion is probably Replenish; although I've also considered Feldon's Cane as an extreme budget option. I think if you're not going to run timetwister you do need some way to get enchantments back from the yard; so I'd experiment with some of these options...

The only thing I would change about this is the Yahenni's Expertise, I'm not sure the free 3 cast is worth much here given your options are kill spells and duress effects, all of which are pretty unsaturated.

Cool deck: First off just observations on the deck; Carnage Tyrant does Nezahals job so its an easy cut. Playing Gift of Paradise over Spring to Mind will help you survive early turns.

I don't see the point in running 2 mana- mana dorks since your ramp curve is 1, 3, 5 not 2, 4, 6. If you are going all in on ramp then Llanowar Elves would be a lot more effective.

Now if you ever decide to run black instead of blue then the following should be pretty useful:

Josu Vess, Lich Knight, Torment of Hailfire, Journey to Eternity  Flip, Liliana, Death's Majesty, Yawgmoth's Vile Offering, Demonlord Belzenlok, Razaketh, the Foulblooded, Moment of Craving, Vraska's Contempt, Cut / Ribbons, Vicious Offering, Unlicensed Disintegration, Yahenni's Expertise, Phyrexian Scriptures, Golden Demise, Fatal Push

I found for dealing with aggro Festering Mummy is insanely good. Can deal with a lot of 2/1s or 1/1s and also trades in combat with 2/2s. To top it all off it is also a great sacrifice outlet.

Frankly, when you have enough mana and reanimation you can start to just ignore your opponents counter spells. With exception to syncopate.

The only thing you'll lose out on is Pull from Tomorrow though if all your cards are mana sinks its a non-issue.

JohnnyCRO on Oona, dos, faes!

Sorry it took me this long to come by your list, I was swamped with work.

I like the clear wincon path. However I think there is room for improvements:

  • you're lacking some staples, namely you need Rhystic Study

  • It wouldn't hurt to add better removal suite; Go for the Throat/Ultimate Price/Cast Down and Dismember are better than Reality shift for instance. Yahenni's Expertise is both budget and effective.

  • cut the conditional counters for hard ones/removal; Daze and Mental Misstep have nothing to do here. Dispel is a meta call if you see a lot of instants, and Mana Leak is the best conditional counter so if you can't reliably hit UU this is a solid one and might be Worth a slot. Spellstutter Sprite requires somewhat of a tribal focus, and with oona being your on ly source of faeries, IDK if this would work in a 75%-ish meta

  • cut the Teferi/Pool combo. it has absolutely no sinergy with the rest of the deck and the pool on its own is very hard to justify. Same is true for Sculpting Steel, it doesn't do enough in a vacuum.

  • you want more lands, trust me. Rework it; leave at least 37 slots for those and do that when you're happy with the rest of the deck. Also stuff like temple of the false god has nothing to do in here unless you have 38+ lands.

  • remove footwear; Oona is your wincon, but it doesn't have to be alive for long for you to win and your overall number of vreatures is too low to warrant this kind of space investment.
