Yahenni's Expertise Discussion

Illuminate21 on XLN - UB Master Control

I'm not really an expert when it comes to sideboards, but Iv got a rough idea of what I want. I'm thinking something along the lines of:

2x Harsh Scrutiny - To be used against aggro decks and any deck that plays Carnage Tyrant.

3x Kefnet the Mindful - Kind of replacing Sphinx of the Final Word, being a control mirror breaker. Also good against midrange decks.

1x Yahenni's Expertise - I'm not sure about this, but I have found that it is better to have a another boardwipe against token decks, mostly Vampires these days.

2x Doomfall - Another answer to Carnage Tyrant, yet also has an discard effect, which might be useful against some decks I hope. xD

3x Negate - Replacing Dispel which was used against the control Mirror, yet also good against Vehicles and pretty much any deck that runs mostly non creature spells.

2x Sentinel Totem - Graveyard hate that I want to test. Only problem is that it takes away both graveyards, causing problems for The Scarab God.

Not sure about what to add to the last 2 slots. If u guys have some ideas, feel free to suggest!

I like Yahenni's Expertise and Arguel's Blood Fast a lot. Bontu's Last Reckoning seems really bad in a tap out control deck. Baral, Chief of Compliance Could be good, but then my opponent's creature removal is still live. I'd rather make them have dead cards in their hand. If I play cards like Torrential Gearhulk in my board, then I can surprise my opponents when they are expecting a creatures control deck.

Radeint Maybe if you had another instant to place in here that worked with this theme you could avoid purchasing fatal push... but as it stands it would be a huge improvement to be able to _remove an opponants combo card _or avoid taking damage.

Unless you're planning on doing something with lifegain, or tapping your creature repeatedly, I do think Dread Wanderer would be an upgrade over Night Market Lookout.

My issue with board wipes like Bontu's Last Reckoning & Yahenni's Expertise in your current deck is that they'll likely kill some of your own creatures. If you decide to go little to no creatures, keeping them in would be fine OR you could think of a work-around like have a indestructible creature like Yahenni, Undying Partisan, or some mechanic like that.

Thank you for your suggestions! I'm not sure why I didn't think of Yahenni's Expertise, it's really good against some of the top-tier decks. I want to keep Negate mainboard because I feel like it and Censor are more consistent, and I would sideboard in Duress and Spell Pierce if it was called for. I also like the idea of a Noxious Gearhulk being copied every upkeep, I might give that a try. Currently I have a 1-of of a Vraska serving as a backup wincon/treasure producer/flavor win. Those menace pirates you get on your way to her -10 are good at getting through when they've only got 1 life left.

I think you might be better off with Spell Pierce over negate, also I like your use of vraska and mechanized production. You'll definitely want Yahenni's Expertise and maybe even Bontu's Last Reckoning as well.

I think you are Straddling two good methods for the deck, the first being all instants and sorceries for control, and an alternate wincon by throwing mech production on a gearhulk, whether torrential, verdurous, or noxious. The second method would be pirates! Arg!

The more I play around with these new cards the more excited I am to try them in my hand. I'm really liking the creatureless mainboard with even more removal and the ability to draw cards or do extra damage with Diplomacy is great. I'm absolutely loving Yahenni's Expertise into Sword-Point Diplomacy. Mana well spent. A double Expertise with a flipped Amulet is -6/-6 to the whole board and also two extra free spells. That's insane. It's really too bad that there aren't any 3 or less cost Curses or Creatures that I want in the main to really capitalize on that for turn 4. I'll have to keep digging to see if there are any other enchantments or something, but Diplomacy is just wonderful. I'm considering 4 Expertise for the main actually, but I'd need some more guarantees and a lot of what I want to play is coming up with 4 or more mana.

Sweltering Suns is better than Yahenni's Expertise here. How often will you really net sweet value out of that free spell, especially if you wipe the board? You really only have Opt and Supreme Will for that, and I don't know if dumping Supreme Will on turn-4 is really the best thing if you're already limiting yourself with the number of counters you're playing. Sweltering Suns to the main and cutting Expertise makes a lot more sense, as Suns costs 1 less and can be cycled in otherwise-dead matches.

Glimmer of Genius is really the best card in the deck, so you should prioritize making that a playset. I'd play 4 Glimmer before 4 Opt, tbh.

For your sideboard, cut Spell Pierce and Jace's Defeat for Negate. Pierce is dead after turn-4 in control match-ups, and not being able to hit Planeswalkers is a big deal. Pierce is much better in tempo/aggro decks for use against control. For you, I'd even say Negate is strictly better, especially given how many times you're going to play control mirrors and both players have 11 lands on the board. Lightning Strike should probably be Chandra's Defeat, which can kill Glorybringer, Chandra, and the most playable dinosaurs with a single mana.

ironeyes yeah I started off playing Yahenni's Expertise because I thought I could get a mini boardwipe while playing a 3 cmc card, like Treasure Map, Kitesail Freebooter ect. However now that I'v tested Bontu's Last Reckoning a bit more, I am able to stabilize quicker than with the Expertise. And it honestly doesn't really matter if I can't play a card off of it, since I might be able to keep a counter up or removal with Bontu's Last Reckoning.
