I would just like to point out that this is not an okay thing to say in case you were unaware. In fact, some people would consider this a horrible thing to say. Here's why: Each person who plays this game is a representative of the magic community in some capacity, and when you poorly represent us with statements like this, it hurts us as a whole. On a base level, this comes across as sexist and exclusive, like you are uncomfortable with conceding even a small amount of card space towards making a marginalized group feel more included. Inclusion is how we grow as a community. Inclusion makes magic better because more people playing equates to more resources that wizards can pour back into this game that we love. I hate to think that even one person has decided to not give this game a chance because of someone's ignorant comment. What you said serves no purpose other than to express that you don't like it when women are featured on cards, which simultaneously reinforces negative stereotypes about gamers and actively discourages people from wanting to become a part of our community. So please, think before you speak. Otherwise you're making us look bad.
I'd look to lower your curve in this deck. I get that this is Commander, but you have more than twenty cards in here that cost six or more mana in colors that don't ramp very well, which probably equates to a ton of time in games spent not actually casting cards. I'd look to cut your cycling subtheme entirely or go deeper on it. As it stands, you've got 8 cards with cycling, two of which are repeatable, and only one of which is reasonable to repeat. It looks like a lot of the time, Astral Slide is going to just be a dead card, but because it's in the deck, you've crammed in 5 bad cycling lands which would be better off as basics.
So I was looking at generals that could utilize Aggressive Mining, and I think I got a little carried away. This is just a list I scratched up in an afternoon, but I jammed it with as many cards that don't mind hitting the yard or cards that generate multiple permanents as I could think of. Of note is the fact that the deck is 100% permanents because a) Shimatsu can't smear himself in the blood of stupid instants and sorceries and b) I went real deep on Pyxis of Pandemonium. I might try to build it on MTGO, because the deck is very budget friendly and I'd like to test it. Also, it could easily do without the Blood Moon, which is probably the most expensive thing in the entire deck (But c'mon, Blood Moon for the Blood Demon). It's fairly land-heavy at 39 lands, and some of the card choices here are pretty weak, but that's probably a result of the all-permanent restriction in a mono-red commander deck. I probably missed some good inclusions, so I'm totally open to suggestions to make this slightly less bad than it is. Anyway, here's the deck in all of its sac-for-value glory:
I think some of your choices in constructing this deck are pretty sweet, but there are a bunch of questionable includes here.
Armory of Iroas is really slow and doesn't grant any other abilities. You probably just want to use Marchesa to add counters to your attacking creatures. I'd replace this with a mana rock.
Elixir of Immortality and Feldon's Cane don't really do anything. I'd probably just jam one of the Eldrazi that shuffle your graveyard back into your library in this spot if I were looking for that sort of effect, especially because you're already running Sneak Attack. If you're trying to protect your graveyard from Bojuka Bog style effects, I recommend Witchbane Orb because it also just randomly hoses other targeted effects as opposed to doing absolutely nothing when your opponents aren't trying to exile your graveyard. That said, shuffling your graveyard back into your library is a pretty hard nombo with Marchesa because all of the creatures that were going to come back due to her ability will now be in your library, unable to return to the battlefield.
Power Conduit Lets you move one counter once per turn cycle from one creature to another, which is kinda cute with unleash I guess. (emergency blockers?) but it seems really weak. I get that a lot of your creatures come back with counters on them already, so you can use it immediately, but taking counters off of your dudes doesn't look like what you want to be doing. There are admittedly very few +1/+1 counter enablers in grixis colors, but Dragon Blood just seems better despite the mana cost being higher. I'd also include Mephidross Vampire over this, too. Plus, it makes your Blade of the Bloodchief slightly better.
Bloodfray Giant and Evernight Shade aren't particularly impressive creatures in Commander. Even if you get them back for free, most of your opponents' creatures will outclass them fairly quickly. Bloodfray giant is at least a little undercosted and has trample, but Evernight Shade is really weak, especially in a three color deck. I can't ever imagine a situation where I want to spend mana to make this guy better than a ridiculously overcosted Grizzly Bears. I think you'd be better of swapping these out with sweet creatures to recur each turn, like Hellhole Flailer (he can sacrifice himself to basically lava axe somebody and comes in with a +1/+1 counter!) and Solemn Simulacrum.
Sage of Hours is never ever going to get to 5 counters unless you do something like immediately pay 15-30 life to Unspeakable Symbol. That actually sounds really awesome now that I think about it, but outside of that situation, this guy would just be better off as a Time Warp if your goal is to take a bunch of extra turns. Especially since you can recur Archaeomancer.
Rockslide Elemental falls into same camp as Evernight Shade, and that camp is called "Overcosted tiny creatures that you have to jump through a bunch of hoops for before they're even remotely a threat."
Oona's Blackguard wants to put +1/+1 counters on creatures so bad, but the only other rogue in the deck is Taurean Mauler, so it just ends up as a Larceny that dies to creature removal and doesn't necessarily affect all of your creatures.
Rage Forger will certainly be forging your rage as you realize that the only creatures in your deck that this puts a +1/+1 counter on are Taurean Mauler and Ashling the Pilgrim, both of which can get +1/+1 counters just fine by themselves. This just wants to be a Hellrider.
Triskelion is pretty cute with Marchesa and a free sac outlet, but a really boring way to combo the table out with Mikaeus, the Unhallowed.
Ordeal of Purphoros is bad. Commander is a format where Lightning Bolt is bad, and this card is much worse than bolt. You'd be much better off using one of the rings from Magic 2013.
Ordeal of Thassa is similarly bad. It's a tall order for a creature wearing one of these to survive long enough to use it. Just run Concentrate or something if you want to draw cards. You've got blue, you don't need to settle for easily disrupted conditional drawing.
Crypt of Agadeem 14 black creatures probably isn't enough to run this. Also ideally, your creatures aren't actually spending much time actually in your graveyard for this to be much better than just a Swamp.
Thran Quarry The drawback here is significant. A basic would be better, probably.

Cards I'd cut:
Barren Moor, Drifting Meadow, Polluted Mire, Secluded Steppe, Blasted Landscape
Replace these with basics or stuff like Temple of Silence and Fetid Heath. It's also probably worth it to get a copy of Urborg, Tomb of Yawgmoth since it's been reprinted in Magic 2015. It'll make Crypt Ghast much better and fix your black mana for activating Greed and casting Necropotence.
More cards I'd cut:
Abhorrent Overlord, Absolver Thrull, Eternal Dragon, Pontiff of Blight, Quarry Colossus, Vish Kal, Blood Arbiter, Blind Obedience, Decree of Justice, Cloudstone Curio, Necromancer's Covenant, Astral Slide, Glimmerpoint Stag
I'd add in some higher-impact low-cmc creatures with enters-the-battlefield effects like Blade Splicer, War Priest of Thune, Stonecloaker, Skinrender, Seht's Tiger, Phyrexian Delver, Shriekmaw, Nekrataal, Kor Cartographer, Entomber Exarch, Angel of Finality, and Reveillark. Though, for Reveillark, I'd probably skew my deck even further towards cheap etb creatures.
