Burn+Wrath+Blunt MDE

Despite being a mono-status team, there is not a lot of flexibility with packs since we need as many good EGO gifts as possible.

Starting Gifts: Fixer Magazine is a filler spot and can be replaced with basically anything else. It is one Blunt Power Up but can be easily replaced by an economy gift or an EGO resource generator. There is fortunately no need to pick up anything rare for fusion reasons.

Floor 1: Automated Factory We're here to fuse Hoarfrost Footprint. Get to Glimpse of Flames as soon as possible.
Floor 2: Hell's Chicken Burn chicken and other assorted goodies. Best floor 2 pack for basically every run.
Floor 3: Full-Stopped by a Bullet Technically flexible but there's not much to substitute in. Darkflame Smoking Pipe and Gear Shrapnel are just good gifts.
Floor 4: Timekilling Time BokGak We are only here for a few gifts, but Microprecision Time Accelerator and Chalice of Trickle-down are the two big ones. This is not the only floor 4 floor you can pick but it's the least cost intensive.
Floor 5-10: Line 2, LCB Regular Check-up BokGak, Textbook, Nocturnal Sweeping BokGak, The Dusk of Amber. It is recommended to take Textbook and Dusk of Amber first, as you require only a couple of EGO gifts from both and can save you cost otherwise. Line 2 is flexible but you should take it if you see Bridle as a reward. We're only at Nocturnal Sweeping for the Blunt gifts and can skip on the Rupture ones, but LCB Bokgak is a fire sale. We, ideally, want every single Burn and Rupture gift here, and also to pick up Modified Extraction : AEDD as well. Heavily recommended to only do this when you're flush with cost.
Floor 11-12: Incredibly highly recommended to grab Chachihu and Complete & Total Extermination first. These are the final boost in power we'll need and will allow us to more comfortably clear the rest of the mirror dungeon.
Floor 13-15: Packs are up to preference, although Bearers of Weight is highly recommended. Any other pack is simply extra and won't meaningfully impact the run.

ALTERNATIVE ROUTE:
Starting Gift: Replace Fixer Magazine and Frozen Cries with Red Necktie and Red Tassle, replace Automated Factory with Faith & Erosion and Textbook with Mnestic Experience. This is more difficult and focuses less on the Blunt side but gives strong damage bonuses to your Slash IDs, of which this team has several.
