These are all done assuming op is running a stock list. If they have weird stuff then adjust accordingly obviously

FULL DISCLOSURE: I DONT ALWAYS SIDEBOARD IN THESE EXACT WAYS

Sideboard

https://www.mtggoldfish.com/deck/2779635#online

In most matchups there is an argument for any specific card

Common GSZ Targets

it depends on the situation, so just because it's not listed

for if you're learning the deck

2 lands (at least 1 makes colours), no dork, OUAT

(not exhaustive obv)

doesn't mean you shouldnt gsz for it

We cut mom because of plague engineer

If you want chalice over sylvan you can but you're wrong probably

4+ lands with OUAT depends on the last 2

Questing Beast

BUG you might get away with cutting a second mom for sword of L and S, I'm trying that out rn

if you see things you need to kill with KOA (like vortex),

Elspeth, Knight Errant

cut mom instead

Gideon, Ally of Zendikar

Questing Beast

Gaddock Teeg

There's a lot of potential targets, because it is very situational

If they have a PW we need to kill, QB

If we have lots of creatures we don't want to lose to Terminus, Teeg

Questing Beast

If they have an active Oko, Scryb/QB could be good

Gideon, Ally of Zendikar

Shifting Ceratops

How the matchup feels

Medium-Bad (45-50%)

Gaddock Teeg

Generally unless they already have the artifact mana/wishclaw out

Collector Ouphe

Gaddock Teeg is the safest as it stops ad naus as well as echo

However this is definitely dependent on their draw and yours

Scooze is basically if you have nothing else good to get

If they aren't running monolith or whatever, cut ouphe and bring in the sword of l and s

Teeg is great against eldrazi stompy, post, and moon stompy, but medium against G POST

against moon stompy only bring in hexdrinker, and leave 2 moms in. because of bonecrusher giant

Thalia, Guardian of Thraben

Scryb +mom is amazing

Fliers are great in general

Questing Beast

QB beats their moms

Ouphe stops vial and jitte

Gideon, Ally of Zendikar

hexdrinker is a game win if it gets max level

(cantrips/removal, removal, oko/deluge, jace and other sweepers

KOTR is a big threat that can pressure their mana, get cradle, and karakas

UG Show and tell

Also could cut moms over stoneforge here since they might not run much removal

Gaddock Teeg

These are matchups where KOA is better than pridemage

If you think they aren't running arcane artisan, you can cut all 4 stp and leave 2 stoneforge 1 skull

Gaddock Teeg

I'd keep moms over stoneforge here for sure because S and S does run several removal spells

Collector Ouphe

pretty much always scooze

KOTR if they have grissy b and you don't have an answer, because that's priority over the gy

Also if you have a different opinion about my boarding/cards in my list, feel free to talk to debate with me about it, I'll be happy to explain my card choices.

Active Mom +scryb Ranger blanks Grizzy B

This seems fine to me but like I haven't done too much thinking about reanimator boarding

KOA Blows up animate dead

Scryb and QB for pressuring OKO

Questing Beast

KOTR for pressuring mana

Sword of l and s is great

we trim on moms becasue of engineer

Thalia, Guardian of Thraben

If you see Sylvan Library KOA stays in

Scryb with active mom beats everything except sejiri steppe,

Thalia, Guardian of Thraben

so its something to keep in mind when stalling for an answer to merit lage

Gideon, ally of Zendikar

If they have Pfire Maybe 1 leyline can come in to meme on them

Thalia, Guardian of Thraben

If you've noticed a pattern, its that Scryb is amazing and

you should be getting it more often than you are.

Also if they aren't running blue you don't have to bring in ceratops

If they aren't running blue then ceratops does not have to come in.

KOA Kills mox diamonds and explorations, Ouphe stops diamond

Scryb with active mom it stops merit lage again

KOTR Is a good default pick

Questing Beast

QB beats maze of ith AND Glacial Chasm

Scooze is very powerful g1 to snipe loams and pfires also.

Literally 99% of the time ouphe

Against legendaries

if they have emry

against echo consider cutting more equipment and some other random stuff to run in leylines

I've played against Food Chain like twice this year, I'm 1-1 against it. Not super sure about the boarding

But this seems like a good starting point regardless. If we find we need more grind to win, add more PWs,

Questing Beast

If we miss moms/ they're running white for STP, keep them in

We don't have good gsz targets really, this matchup is bad im pretty sure.

This is one of the few matchups where KOA is worse than Pridemage

Depending on the deck you should bring in/take out these cards

Keep in mind they all run at least 2 plague engineer

4c no white stuff

KOTR to pressure mana

Scooze to tax gy and turn of snap

Scryb/QB for pressuring OKo

Hexdrinker as a threat

Thalia, Guardian of Thraben

Scooze most the time, ouphe if they have altar

KOTR to deal with gaak

Always scooze

Honestly I do not know this one is hard to hate out, thalia is probably our best card

We definitely want to be able to clock them still

Gaddock Teeg stops force+snuff out, but I don't think thats enough to keep it in
