My Winning Silent Card Strategy for Ascension 10 in Slay the Spire 2

You might be curious why this isn’t labeled “the best builds for Ascension 10.” The truth is, while builds are still significant at higher difficulties in Slay the Spire 2, they can be misleading—Ascension 10 isn’t just about achieving perfect synergies; it’s about patching up weaknesses. Your starting deck has its flaws, and you need to address them quickly.

I’ll dive into Silent’s builds later, but at Ascension 10, it’s more beneficial to grasp which cards can help you cover your vulnerabilities. In other words, these are the best Ascension 10 cards for Silent—not necessarily the best overall, but the ones that will help you survive the quickest. Let’s get into it.

I’ve conquered Ascension 10 in Slay the Spire 2 with every character at least once, which puts me in the unique position of being the go-to expert on how to excel in this roguelike deckbuilder. Today, I’m sharing that expertise, starting with the Silent, the poison-wielding rogue.

The Silent’s most potent mechanic is the Sly modifier—when you discard a card with Sly, it still activates. However, there’s a catch: you typically want to avoid picking up most Sly cards until you have reliable discard options, as they often don’t justify their energy cost on their own.

If you accumulate too many Sly cards early on without ways to discard them, you’ll essentially be creating your own curses, leading to disastrous hands that can cost you dearly in Act 1.

Beyond that, the general strategy for Ascension 10 remains consistent: prioritize early damage and 1-2 AoE cards, secure solid defensive options, and then focus on card draw and discard to enhance your hands each turn and set up Sly synergies.

These cards may not be game-changers on their own—some might linger in your deck for the entire run, while others may lose their usefulness as you progress. But remember, this is Ascension 10—you need to address your weaknesses as soon as possible, regardless of whether these cards fit into your envisioned build.

Early value is crucial. In the initial floors of any run, your goal is to acquire cards that outperform a strike—because strikes alone won’t deal enough damage to handle Ascension 10’s tougher, tankier foes.

Once you’ve secured some early value, it’s time to solidify your defense. Damage in Ascension 10 is punishing, and you’ll likely take chip damage in nearly every fight, meaning you’ll be resting at campfires more often than upgrading your cards. Establishing an early defensive strategy not only helps you avoid damage but also strengthens your position for the long haul.

After setting up your defense, the Silent should focus on their draw/discard mechanics—Sly is your ally, which means discard is essential, and card draw is a solid safety net for any character. Good draw reduces the chances of wasted turns, which can be deadly in Ascension 10.

Finally, consider ramp and scaling—this refers to “things that let you play more cards earlier in the fight” and “things that enhance your existing damage or allow you to grow stronger over time.”

I wouldn’t label any of these cards as bad; most are useful in Slay the Spire 2. However, they can be situational, so ensure you pick them only when you have the other cards or relics that make them effective.

To win Ascension 10 runs in Slay the Spire 2, focus on solutions rather than rigid builds. Sticking stubbornly to a specific archetype can lead to defeat. However, it’s still good to keep archetypes in mind, as you’ll likely be steering toward one of these versions of Silent during your playthrough.

If you get an early Kunai or Shuriken relic, it’s worth building into those, as they provide inherent Strength and Dexterity, which the Silent can leverage effectively. Shiv decks typically rely on cards like Fan of Knives, Accuracy, Phantom Blades, Blade of Ink, and Afterimage, along with cards that generate shivs, such as Hidden Daggers.

However, due to the number of supplementary cards needed, it’s only advisable to focus on Shiv if you have those relics or lack other synergistic options.

The second-strongest archetype, poison, is quite effective. It inflicts damage right before the enemy’s turn and has built-in scaling. Poison decks mainly struggle with AoE damage and can be a bit slow to ramp up.

You should build for Poison if you acquire key cards like Corrosive Wave, Accelerant, Bouncing Flask, or an early Bubble Bubble—or if you gather relics that provide block, allowing you to survive long enough to stack up poison.

The strongest archetype for the Silent is undoubtedly Sly, which is incredibly powerful and synergizes well with card draw and discard mechanics.

Even if you’re leaning toward Shiv or Poison, you’ll likely have some Sly cards in your deck, and many of the best cards for Silent—like Adrenaline, Calculated Gamble, Tools of the Trade, and Hidden Daggers—are naturally Sly enablers.
