Yahenni's Expertise Discussion

Brogan54 on Oloro, Ageless Ascetic

My recommendations :

I think most people will tell you that Oloro offers little competitive advantage to you compared to other esper commander like Zur (who can fetch Necropotence into play) or even Aminatou (who is a combo piece in the command zone). I think upsides for Oloro would be that he can do larger ad nauseam and possibly can even run Humility which few decks can win while it is on the board.

Debt to the Deathless

Decree of Pain can refill you hand at the same time, to fill up with gas after the boardwipe.

In Garruk's Wake has high CMC, but only affects your opponents.

Yahenni's Expertise and Maelstrom Pulse can hose down tokens.

Hey cerobins5 - I'd probably just drop two copies of Dead Weight. Ideally, you'd also want to sub in at least a couple of sweepers for Murder. If not Bontu's Last Reckoning, at least something like Drown in Sorrow or Yahenni's Expertise.

Hey, Cinestra!

I was wondering if there is any particular reason you run Damnation over Languish or Yahenni's Expertise ? Thanks in advance and happy holidays.

Testing Yahenni's Expertise instead of Humility , Mirrormade for utility and replacing Hushbringer for Aven Mindcensor

Seems like Mission Briefing could actually be useful in this deck, maybe as 2x instead of a Negate and something else? Also, just because you have three colors, you may need to add an additional land. Maybe not on the land, but it just feels like it might need one more?

In the sideboard, maybe Doom Blade instead of Yahenni's Expertise ?

Just a couple of quick thoughts.

Did you have a look at the currently testing section? Tracker is actually in it already.

I just really dont know about the DRS cut, considering DRS is what it is in the later game. I can test, but you were right in saying I dont like it, lol.

The inspector is interesting for sure. I'll do some testing with it. Now that Field is banned, Witch's Vengeance is an easy cut for Yahenni's Expertise , aside from the occasional elf or knight deck. But those are few and far between so I'll make that cut.

Any other ideas?

I don't see much change in this list.

You won't like it but I would still recommend getting rid of one Deathrite Shaman and putting one Sandsteppe Citadel in its place.

You just don't want that Creature early in the game.

Have you considered Yahenni's Expertise instead of Witch's Vengeance ?

I can see why you have it - to protect your Creatures while getting at least some board wipe of the other field of something like Zombies, but it does have its limitations.

I just noticed that you have no card draw. We've been using Tireless Tracker in StuBi's deck to excellent effect. You really need some for games that go long.

Questing Beast or Scavenging Ooze could be removed for it, depending on which one you find less useful.

If it were me I'd take them all out, but it's dependent on taste and play style.

Hope that helps.
