Covenant 25: Help me lean on Umbra less

[Kittens]

So I beat C25 with each clan as primary, but I found myself bringing Umbra along every time except one. Umbra has excellent cards for clearing out dangerous low health enemies, morsels are super versatile, the artifacts are great, and Collector is often a good Seraph killer. Awoken brought Hellhorned as ally instead, as Awoken have their own tank in Thorned Hollow. Stygian win used Hoarfrost Effigy but had a Collector as backup.

What I would like to know is: Which ways do you look for to beat Covenant 25, other than Collector / Frostbite / Thorned Hollow?

I had decent win streaks on cov 25 using strategies outside the ones you listed, feel free to check out these breakdowns I made of them:

I typically do double random clan at Cov 25 and this is what I usually aim for:

Hellhorned

• Rage build, spam Ritual of Battle and Dark Deal, Enflame is meh, but not ideal. (Still hurts against Seraph Chaste)

Awoken

• Regen build, where you spam Wildwood Sap and/or Spreading Spores, possibly Awake on something with 60+ health (Seraph Chaste & Seraph Patient makes it less viable)
  
• Raw damage build, where you spam Razorsharp Edge as much as possible on a Multistrike unit
  
• Adaptive Mutation has a nice interaction with Rage, where the new health is based off the rage-boosted attack. I've gotten a 500+/500+ Animus of Will with three mutations and ~40 rage with Deranged Brute.

Stygian Guard

• Spell Weakness build, where you pray for Multistrike on an Icy Cilophyte, dupe it, and then try to get a big spell with Permafrost. If you pull an upgraded Icestorm with Gifts for a Guard multiple times, you might it to 90 x5; add Weakness x9 and it hits for 4500.
  
• Many Spells build, where you play many low cost spells on stuff with Incant and hope you get Multistrike on your damage-dealing unit.
  
• Frostbite build, spam frostbite & win. I rarely do it because I usually get drafts that lead me down a different path.

Umbra

• Lifesteal/Damage Shield build, shove as many morsels into an upgraded Collector, woo. If it's Seraph Patient, I'll run Warden instead since Damage Shield is better.
  
• Overgorger build, where you shove all your resources into Overgorger and dupe it.
  
• Primordium can be reformed by a Remnant card if dies normally, so you can hit it with Antumbra Assault or Cannibalize and reform it to refresh Buffet charges. Although it's usually not worth it.
  
• Also Morsels don't count for Harvest if they're eaten, but they count if they die any other way, so that's cool.

Melting Remnant

• Stealth build, Molten Encasement with Endless (Burnout is also nice) and/or spamming Engulfed in Smoke. You'll probably be lacking in resources to kill minions, but Crushing Demise is a pretty good card.
  
• Legion of Wax build, good upgrades plus Intent on Death is pretty good.
  
• Harvest build, spam expendable minions and hope your Wickless Baron (or Big Sludge) ramps hard enough.
  
• Daze build, if you get Dripfall + Iron Dropcage or Mortal Entrapment + Volatile Gauge then you upgrade and dupe. (This really sucks against Seraph Chaste)

These are just general builds irrespective of Champion, so I didn't include anything specific like Imp build, which btw makes Seraph Patient basically free. For credibility, I'll say my highest win streak for double random is 11, although I do save scum since losing due to terrible deck order sucks.

Other notes

• Upgraded Dante wins runs.
  
• Spikedriver Colonies upgraded before being duped wins harder than Dante.
  
• Why do Automatic Railspikes not have piercing? They're literal spikes.
  
• Everybody who says Seraph Patient is bad doesn't realize that Seraph Chaste ruins more builds and casually poops out about 350 health per wave while Seraph Patient poops out about 200.[/list[
