I'd like to know your experiences with Kari's Expertise.

So far, the card has underperformed for me. Act of Treason-type effects don't seem great anymore; the card has been dead in my hand more often than not.
Maybe I haven't found the deck to play the Expertise in, but currently I don't think that deck exists.

I think these kind of effects are only good when you can sac them after attacking and there isn't a reliably/cheap way to do this.
Otherwise its just a situational finisher, very limited in scope and card disadvantage. That's basically why I was disapointed with the red expertise.

I saw it for the first time today; had my +1/+1 counter draw dude stolen and Kari Zev herself played for free but then I won the game soon after.

Its good with the Valor Boros deck as you can play it into dragon fodder to get extra attacker.

I'm sure it's the worst Expertise, but what kind of deck did you try it in? More aggro or more Crats (help get lethal swings, or steal-attack-sac)?

I have been ok (not build around happy, but ok when it finds a natural home) with Eldrazi Obligator in more aggressive R/X/colorless decks. Red Expertise could play similar roll when combined with something like the speed racer pilot... don't think a deck like that would be top tier, but maybe playable.

I'm sure I'll try to make it work in a sacdos deck. Haven't really messed around much with those since Origins, but am curious to revisit with new toys.

Comparing it to the others:

Yahenni's Expertise - Requires you to be behind to be amazing, can clear a few blockers at the cost of hitting for less in midrange decks. Probably fits into most archetypes running Black.
Baral's Expertise - Amazing tempo swing, great sweeper replacement in control on curve, less value than Planar Outburst later on though. The 4cmc clause allows you to follow up with more relevant threats.
Sram's Expertise - 3 bodies to block or swing, can fit into most White decks, although it may not be the most efficient card in the slot.
Rishkar's Expertise - Winmore most times, but can draw into gas that can then stabilise you. Requires more than your average 2-3 drop to be amazing.
Kari's Expertise - Unlike Rishkar's it helps you win, albeit in very niche scenarios.

Yeah, its the worst, but Green isn't too far behind.

LMAO at Rishkar's Expertise being win-more. That is a trash af opinion. It's an amazing 6-drop and it's like Ramp's big payoff card.

If you think it's win-more, you're using it poorly.

Kari's Expertise does great work in Vehicles; steal their permanent and then play a copter/Kiran/1-2 drop for free.

I'm not really seeing it's strength from a theory standpoint:
I'm probably casting it the turn I want to close the game, so the two-one mana card is something that can affect the game that turn, like something with haste or a burn spell.
AND I haven't found a better time to deploy that two mana card earlier/have topdecked it that turn.
AND I don't have enough mana in play to cast all the spells that can affect the board that turn, so either I haven't hit my fifth hand or I have 3 spells in my hand, and are interested in casting a threaten effect.

It seems really situational.

This x1000. Rishkar's is absolutely fan-freakin-tactic. It's my favorite card of the expansion so far.

The red expertise under performed when I tried it. It sucks.

Cats and dogs...

Fell in love with Rishkar's expertise as well. Its a much needed card for green stomp. It can be casted early with Druid of the cowl. When cast it can stabilize the board by giving you:
an extra large creature like Reality Smasher and Ridgescale Tusker
planes walker to turn things around like NIssa Vital Force or Gideon
vehicles like skysovereign for free

Allowing you to draw first makes it much more likely that you will have something good in your hand. Its an indirect wincon on its own.

A card that requires you to have decently high power stuff already on the board? In a deck that could just draw into more ramp spells? Where Ulamog, Gaea's Revenge, Greenwarden et al are all above 5cmc? Sounds more like a midrange card to me.

I'd say it's passable at 2 power (2 cards and a free 4-5 drop is acceptable) but that is about worst case scenario, i've played a bunch of ramp games and usually i'm hitting for at least 3, and any more and it pretty much reads "win the game within the next couple turns"

It works great in aggro decks like vehicles; I love casting it when I have Thopter Engineer on the field and playing Kiran/Copter for free; giving them haste in the process along with the stolen creature.

You're right. Ramp certainly has no relevant spells 5 cmc or below, because we're all incompetent deckbuilders with no understanding of what a curve is.

Someone shat in your coffee this morning Vert?

What gives you the idea that a ramp deck should only play 6+ mana spells? Or only spend the first 3-4 turns producing mana? Your lack of experience and hatred of the archetype is showing.

Doing nothing but ramping and then spending all your mana on one big dumb creature is how ramp decks lose. The Sylvan Advocates, Tireless Trackers, From Beyonds, Vital Force/Gearhulk, etc. have a place too. Notice the trend? These creatures all have relevance post ramp, or because of ramp. Advocate grows, Tracker poops clues and grows while ensuring our gas, From Beyond ramps and fetches, Nissa and Gearhulk are legit win cons. You can slam all these things late game too if the coast is clear to ramp early, and they're still relevant too.

Now.. here's where Rishkars Expertise shines. You blow all your resources ramping, curving or whatever.. and now you're out of gas.. in topdeck mode. You're vulnerable to a Planar Outburst type effect, drawing more land, mana dorks and ramp spells is horrible. So.. you cast this, reload AND play a solid threat. You're either right back in the game, or poised to out resource even the most well-supplied control deck. I've actually cast it and fired off a Planar Outburst a few times now, drawn 4-5 cards.. and been way ahead on resources because of it.

I don't understand how a person who identifies as a blue player, can hate on a spell that draws a ton of cards AND puts a win condition in play at the same time. I think you're just jealous that blue doesn't have anything near as powerful of a draw spell as Rishkar's Expertise.

It's odd that you both say I "hate" the spell, or call it "bad". Where did I say that? I can't seem to find it.

I think someone shat in your coffee too Beast

I think you're awfully sensitive this morning. It's 3:30am.. I haven't even been to sleep.

Anyway.. it's an amazing card. I'll say it again.. it's like Confirm Suspicions, it puts you ahead on resources, while doing what your deck wants to do in the first place.
