Best affinity hate in black or white

[Nyzzeh]

I'm looking for good hate cards against affinity in white or black. Kataki is probably the best one, specially if they don't run red, but it costs nearly 20$ on mtgo and I need some other cheaper solution. I've probably already looked at all the solutions, but I'm asking just in case I forgot something.
I'm also looking for something that also deals with other decks at the same time. These are the cards I've considered (other than kataki):

Damping matrix: probably too slow, even if it's good against pod and twin. I've tested it and the problem is they can cast and equip the overpowered equipment before this comes into play.

Suppression field: same as matrix, comes earlier but lets them equip and activate manlands for and ravager sac for .

Stony silence: seems like the best other than Kataki, but doesn't help much against other important decks that I can think of.

Fracturing gust: seems too slow.

Disenchant: seems not good enough, specially now that I've seen welding jars around.

Unless they're running Tempered Steel, Elesh Norn, Grand Cenobite shuts them down hard. But if you don't have a way to cheat him into play, other -1/-1 and -2/-2 affects are easy to come by in BW, and can be a total blowout.

Zealous Persecution, for example, can kill all their memnites, vault skirges, and signal pests, along with a random overseer or activated inkmoth, while buffing your spirit tokens so they can eat any left over ornithopters.

Infest is usually a 3 mana Wrath of God against them, as well.

Disenchant is really good against them too, but it only trades 1-for-1, so it's never a blow out.

[Nyzzeh]

Ye, I've built bw tokens and I'm currently running 3 persecutions main, but they don't kill the plating. But can't complain, I'll probably add a couple stony silences SB that also help against explosives recursion if nobody gives me a better solution.

[Goryus]

Pithing Needle is a 1-mana answer to an arbitrary number of platings. Just be aware that some affinity lists have started running Ancient Grudge in the sideboard for the mirror.

[Nyzzeh]

Uhm hard decision between silence and needle. The neddle also helps against pod, explosives, etc, costs 1 less but you have to choose between ravager and clamp.

[naykos]

kataki is the best but you can try:
aura of silence
Circle of Protection: Artifacts
fracturing gust
if you see welding jars around, try purge
if stony silence is dead against other decks, try pithing needle
but zealous persecutions looks like a one sided wrath agains them, well exept for ravager but can you chump it until you find some dedicated hate card against it right?

[Nyzzeh]

I'm not even sure kataki is the best since they almost always pack galvanic blast.

I find the real problem cards in Affinity for W/x Tokens are Etched Champion, Arcbound Ravager, Master of Etherium, Steel Overseer, Tempered Steel, Tezzeret, Agent of Bolas, and Cranial Plating, with Signal Pest being the most threatening non-threat. Even Plating is non-threatening if you can keep it off Champ. This is why I think better hate than Zealous Persecution should be used against Affinity--ZP only kills everything Midnight Haunting also squashes.

...Although Affinity sometimes gets those nuts-fast starts, yes. But I've found that W/x Tokens can deal with any opening hand that doesn't include any of the above. And even the Ravager-as-biggest-threat hands are suspect, quite frankly.

[Nyzzeh]

Etched champion why? It's only dangerous with plating, which is the most scary card.

[Lectrys]

Etched Champion can almost never be chump-blocked and is extremely scary with Ravager counters on it (you can't even make Shrine of Loyal Legions tokens trade with it when this happens). I usually aim PtE at Ravager ASAP because of this interaction.

Frogmite is a joke. Champ is not simply because it has protection from all colours.

[NidStyles]

Wrath of God Damnation + Revoke Existence for the Cranial Plating. These are obviously sorcery speed, but by far the best options against the deck in those colors.

There's also Return to Dust. Ghostly Prison to slow them down.

[Azulah]

Stony silence is the best affinity hate...better than kataki I think. They can't blast it and with kataki they can still equip and attack, ravager, overseer, drum, or mox. Makes their whole deck small vanilla creatures more or less. It has uses in other matches too btw. It's good against pod, tron, and scepter decks to name the best decks I can think of off the top of my head.

I've been playtesting various Affinity builds all week while prepping for GP Lincoln and Kataki is by far the one thing I do not want to see across the table when I'm playing against white. The bottom line is that Affinity depends on lots of artifacts to win (whether to swarm an opponent, to power up a Cranial Plating, or via metalcraft) and Kataki attacks that most directly.

Wrath of God (and Infest as previously mentioned) are solid especially in that they take care of Etched Champion, but are weak in that they do not affect Bl/inkmoth Nexus.

Darkblast early game can also wreck many Affinity builds, but is weakened by Spellskite.
