Had a VERY satisfying run with Defect. 4 claws, 3 All fir One's, 1 upgraded hologram. 2 upgraded buffers for defence with an amplify floating around. Ice cream made the whole thing operable

[esbernhawkins]

Made a drop kick infinite right after watching this video, so thanks for that! 2 Drop Kicks + Double Tap gave me a way to infinitely cycle Ethereal Armor, so I was even able to beat the Heart with it.

I'd like to note for new players (like me) trying to make an Ironclad infinite deck: DO NOT ignore exhaust cards. Fiend Fire was consistently clearing 9 cards from my deck (thanks to my draw power, anyways), which was helpful for dumping my Defends and cards that were good for setup but not for the combo (e.g. Battle Trance).

[SilentScyther]

It's worth pointing out that Ironclad has a ton of exhaust cards so even if you can't get your deck down low enough for a one turn infinite, you can use something like Fiend's Fire to exhaust most of your cards so you can go infinite the following turn.

Thanks for the video, most other StS content is an hour or longer. I appreciate your work!

Defect's most reliable infinite is Recursion with a Plasma Orb, from Chaos, Fusion, or Nuclear Battery, supported by Coolheaded, Compile Driver, and Skim for card draw, most of the pieces to this are common/uncommon, compared to needing to a find a Rare Relic, it's way easier to assemble

[Smallpriest]

Just wanted to mention this because it was my first watcher infinite:
2x empty mind
2x prostrate
1x any damage (ideally conjure blade)

Double empty mind and prostrate literally gives you infinite mana and block, the only thing you have to worry about is Time Eater

[machixius]

beating an intangible enemy with finisher is wild

[hectormeneses]

I have never actually built an infinite deck but I get the idea. Great content 👍

I find going infinite on Ironchad the easiest because you don't need to watch deck size as much because pf his easy access to exhaust. Fiend fire, corruption, second wind, burning pact, sever soul, and true grit+ all make it easy to trim your deck down to just your infinite pieces.
My favorite infinite is a silly one with reckless charge, evolve, dark embrace, and medkit.

I realise it’s really not that deep but saying to specifically aim to get an unceasing top to go infinite on defect is a bit strange considering its a rare relic which can do relatively similar things on any class. There are ways to go infinite on defect without relics, most commonly by exhausting the deck down to few cards with recycle, then combining turbo+ with another draw positive card like skim alongside really any 1 or 0 cost damage card. Alternatively there’s ways to go infinite using plasma orbs too

[gengarisnotinsmash...]

Probably my favorite infinite deck I've achieved was on the silent. I love the silent's non poison or shiv damage sources, and as such you will commonly see me take sneaky strike and eviscerate. But on one run I had two reflex+, two prepared+, three after images, and an eviscerate. I knew this deck would be best if it was slimmed down a lot, so I prioritized removes, but I didn't realize what was happening until I realized I had played prepared like 10 times in a single turn. Unfortunately I didnt't quite have enough removes to have a true infinite against heart (if I got unlucky with draw order I'd draw statuses instead of prepared), but I think I was able to get at least one infinite turn against it. And eviscerate hits hard enough that I didn't even need a full infinite.

[D__O]

I just recently got a Defect infinite that was maybe the coolest infinite I've ever had. Meteor Strike, Enlightenment, and two copies of Skim were the big parts. Start by playing Skim to get all your other cards in your hand. Then play Enlightenment to reduce th cost of Meteor Strike to one, and play it to channel 3 plasma. If you either have Nuclear Battery or at least two more energy from relics, play the other skim to draw Skim, Meteor Strike, and Enlightenment. Then, play Meteor Strike again and gain 6 energy from plasma. Repeat the process of Skim and Meteor Strike infinitely.

If either Skim is upgraded, you can add in a Leap or another block card to also infinitely scale block with this.

[FukurouYGR]

I feel like the cards for the infinite decks are just rarer in general. I've been trying to get the Watcher infinite deck for 2 hours now and didn't manage to lol

[williamclancy-jundt]

Fun one I found which isn't really an infinite but doesn't really let your opponent attack either is upgraded nightmare on bullet time, Bullet time, nightmare on nightmare, nightmare on wraithform, wraithform. If you do that on the first turn and have a way of dealing damage every turn like Noxious Fumes or Mercury Hourglass along with something to mitigate damage like oracalcum bird-faced urn or especially titanium rod, then you're just invincible and eventually win. If you have either the smiling mask or piece pipe and the Ring of the snake not upgraded and the bag of preparation then it works even on endless.

[hourgames]

CAW CAWWW! What's your favorite Infinite deck, and why is it CLAW?

[ssjrebox]

Alternatively for the defect, you can use a madness on a hologram to make it 0 cost for the rest of combat. Then you only need hologram and turbo in discard with all for one to infinite. As all for one grabs hologram, which then grabs back all for one. And turbo gives you the energy for all for one.

[CadaverLordSupreme]

One of my favorite runs was prismatic shard run where I got an establishment as the defect with an Equilibrium. Made my coolheaded free along with Sundial.

[HaiLongNguyen-zjpq]

The problem of all the the silent is if you go infinite run with "Endless" mod activated. After few rotations u'll get the debuff that restrict you to play with no more than 15 cards each turn. So the key to really go infinite with the silent is wrath form.

[SkylarkGSH]

Hey, time eater called, he says you have until 12.




But regardless infinites are beautiful and intricate strategy in slay the spire. And scaling is the utmost importance to infinites. Relics like kunai and shrunken are clear examples of this. Because it's not a good infinite if you can't defeat the heart or let alone time eater.

[Jcdlf]

for defect you can basically just get infinite mana with recycle skim. then double energy into tempest for the one shot. add some expensive cards to recycle preferably meteor strike. 2x skim 6 card deck with 2xmeteor upgraded recycle and 2x double energy can one shot any boss with a tempest.
