You need to get down to 60, 63 is just silly.

The tapped and shock lands need to go, there's just no reason for either of them in affinity.

-2 Crumbling Necropolis -1 Blood Crypt -1 Watery Grave -1 Galvanic Blast -1 Ensoul Artifact -1 Etched Champion -1 Master of Etherium -1 Memnite

+1 Signal Pest +1 Blinkmoth Nexus +4 Springleaf Drum

This deck looks fucking nice!!

Signal Pest Is like my least favorite card tho I would also run Frogmite andMyr Enforcer

but a Signal Pest with Cranial Plating thats been hit with Steel Overseer once or twice is hard to stop. Myr Enforcer may be dropped for free on turn 3 but it can be blocked.. at least the pest can evade something .. i dunno... it can be Shock'd though i guess..

idk but 19 lands is way too much for affinity I'd recommend around 15-16 since as previously said mox opal is always a land. other than that all i can do i say take a look at I robot

2x Batterskull looks like two too many. Also I don't think most competitive lists run a full 4x Etched Champion, but I might be wrong. Also more Arcbound Ravager would be good. Have you checked out mtgtop8 to recent tournament lists?

I think you need a 4th Blinkmoth Nexus and are running a few too many lands.

I'd go up to 4 Arcbound Ravager for sure. It's your 2nd best finisher and all lists I've seen run 4. (I'd drop 2x Ensoul Artifact for them.)

Also, why Crumbling Necropolis? You really don't want a tap-land in any ultra-aggro modern build. I would remove it as you have too many lands anyway.

As far as mana fixing goes, you don't really need the shock lands either. I would replace them with those 2 and the tapland with 3 Springleaf Drum. The drum is faster and it adds to your artifact count. With 3 drums, you have 11 5-color mana sources which is plenty.

You should drop all lands that enter tapped and maybe take a look at Frogmite.

If you aren't starting to carve out chunks of health on turn 2, you're doing it wrong.

Done some editing .. please take another look. Still thinking about frogmites

It feels a lot better now with those changes you made. I played about 20 hands and ended up with copies of Mox Opal a few times. I only run 3 in my own affinity deck and that has always seemed to be enough.

I'd definitely recommend adding more Arcbound Ravagers as those are one of your best weapons in the deck.

Even though they are apparently unfashionable for affinity these days, I still swear by my Vault Skirges. A couple of those in your sideboard could be a good choice against similar fast decks.

Anyway good work on speeding this up. +1

I'd replace the 2 Ensoul Artifact with 2 more Arcbound Ravager

Don't EVER listen to a trash player who tells you to have any less than 4 Cranial Platings. That is asinine lololol

Shrapnel Blast.

Any viable alternatives now that Mox Opal is modern banned? I know Hardened Scale but that's not quite the same

Baellionaire !! whattttt i've been out of the game for a bit, are you serious? that sucks
