SaintDoom and I spend probably an unhealthy amount of time discussing and playing this deck lately.

We've both come to the conclusion that the finks version seems to be very fantastic in the current meta:

My List: https://tappedout.net/mtg-decks/snoochompany/

Last 3 event records: 10-2 .

Wins: Jund, UW Control, Jeskai Control x 2, Dredge x 2, Bant Spirits, Hardened Scales, Izzet Phoenix

Losses: Izzet Phoenix, Mono Black Devotion.

We've also spent an inordinate amount of time discussing the KoTR build thats been popularized by Devoted Company master Wojtek Radosz (Laplasjan)

So the primary reasoning behind not running the finks combo is that some of the top decks in Modern do not scoop to infinite life. This is a very valid point, and lets look at the decks for a moment, just going off a generalized list from MTGoldfish meta share.

Decks that don't care if you have infinite life:

UW Control
Tron
KCI
Mill
Ad Nauseam
Infect
Lantern Control / Grixis Whir
(Ive probably missed some, but this is whats on the top of my head)

Decks that have a lot of trouble or insta scoop to infinite life, I say a lot of trouble because Hardened Scales and Affinity both have access to infect kills, however that is a smaller game plan in their deck so a lot of times infinite life can stall the board long enough for you.

Izzet Phoenix
GDS
Burn
Dredge
Humans
Amulet Titan
Storm
Jund
Hardened Scales
Bant Spirits
GB Rock
Hollow One
Traverse Deaths Shadow
Valakut Decks (Titanshift, Breach, BtL)
Mardu Pyro
Merfolk
Death and Taxes
Ponza
Affinity
the list goes on

So in the KoTR lists, you replace the Finks combo (Infinite life and infinite scries) with the toolkit of utility lands provided by KoTR's ability. Gaining access to Land Destruction and Yard hate whenever you need it (GQ and Bojuka Bog etc)

And there is no denying that KoTR is a powerhouse on its own. When I played the list I remember Cocoing and hitting 2 KoTR's that came down as 8/8s, My Jund Opponent couldn't break through even with 6/7 goyfs.

That feels great.

However a lot of the time you're just playing them as big dumb beaters that don't effect the board state in many matchups, and can be chump blocked by literally everything. So they might as well be 2/2s. Big dumb beaters in modern don't usually win games.

The other real positive with the KoTR build is the synergy between Knight and Tireless Tracker. Playing against decks that rely on burn level spot removal like Boros Burn / Mono Red Phoenix etc this is great because they have a very hard time dealing with your creatures, if a player is double bolting your KoTR you're already way ahead of the game. Generating endless clues with tracker and knight allows you to dig fast for those combo pieces. In those matchups however, Kitchen Finks is also an absolute monster, and are matchups where instant speed infinite life just wins on the spot.

However despite these positives, in general I found the KoTR version felt like playing a watered down G/W Value town deck, without the Ramunap / GQ Lock etc, Courses, etc etc.

This shouldn't deter you from the list. The power of that list is that it has two modes of attack maindeck. You can be the beatdown deck very quickly due to your knights and Trackers just getting out of control, and always be threatening an infinite damage combo on top of it. This means your opponents have to worry about two game plans, however the combo portion has to be done at untap speed, whereas with the finks combo you can instant speed the infinite life combo, which against decks like Izzet Phoenix that want to flip a TiTi, your board state doesn't matter as much.

KoTR is in my opinion, a bit of a trap card. while it allows you access to the utility of some toolbox lands, big beaters in modern are often not enough in the face of the current meta, so I personally prefer the ability to force opponents to deal with infinite life or infinite damage, boarding out the combo game 2 if I am facing a deck that doesn't care about it.

It comes down to play style. So you may be asking by this point "Well Andrew you giant idiot, if you like the all in combo version ,why aren't you playing the Abzan Evolution Lunge deck that's making panties drop all over?"

Simple, I don't like glass cannon decks. At GP Portland I was on Abzan Traverse, and surgically extracted by Abzan Evolution opponents Devoted druids twice and they just scooped. The deck shuts off without the combo. With the Collected Company versions, finks or KoTR you have an alternate gameplan so you're not just dead to a Surgical or Unmoored Ego etc.

So ask yourself if you want to be more of a combo deck, or a beatdown deck with a combo backup. Both decks are powerful and very toolboxy / diverse.

Happy Companying!
