Anime Card Clash Update April 2026 — Demon Invasion & New Cards

By Earnaldo Team • April 7, 2026 • 9 min read

Anime Card Clash dropped Update 6.6 on April 2, 2026, and it's the biggest shakeup to the game's PvE content in months. The headline feature is Demon Invasion, a brand-new game mode that completely replaces the old world boss system. Alongside that, two ultra-rare cards join the gacha pool, Battle Towers received a major ban list overhaul, and several quality-of-life improvements streamline the deck-building experience.

This is the second half of the game's Anniversary celebration, following Update 6.5's Fireworks system and Heavenly Moon cards from March. Where Part 1 focused on collection events, Part 2 is all about a fresh endgame loop.

What's New in Update 6.6

Demon Invasion Mode

The old world boss system is gone. In its place, Demon Invasion introduces a self-contained PvE experience with its own roster, inventory, and progression track. Think of it like the dungeon system but built around wave-based combat and elemental strategy.

Here's how it works. You recruit Holy Knights from 4 elemental banners in the Demon Invasion UI's Recruit section. Each player gets one free pull, and subsequent pulls cost Yen. You can pull x1, x5, x25, or x100 Knights at a time. These Knights exist only within the Demon Invasion mode — they don't carry over to your main deck.

Team slots start at 2 cards, and party slots start at 1 party. Both can be upgraded through mode-specific progression. Knights gain +20% stats per tier upgrade, with ability upgrades unlocking at 3-star and 5-star tiers. Building toward those thresholds is what drives the early grind.

The core objective is reducing the invasion pressure bar. Harder missions cut more pressure, so there's a constant risk-reward calculation. Pushing into tougher missions with an underpowered squad means risking a wipe, but playing it safe means slower progress on the pressure meter.

You can't switch or edit teams mid-battle. Whatever you bring into a mission is what you're stuck with for every wave. Planning your elemental matchups before you start is essential, not something you can adjust on the fly.

Two New Ultra-Rare Cards

Update 6.6 adds two cards to the main game's gacha pool. Both sit at the extreme end of rarity.

King of Chaos edges out Commandment of Love in raw stats — 240 more HP and 120 more DMG — but it's also rarer. Both cards are in the same stratosphere as the existing Heavenly Moon cycle cards from Update 6.5. Getting either one requires serious luck stacking or a massive number of pulls.

The Greater Moon Cycle Potion from the previous update targets Heavenly-tier pulls, which includes these two new cards. If you stockpiled potions from the Fireworks event, now is the time to use them.

Battle Tower Ban List Changes

Battle Towers now share the same ban list as infinite tower bosses. The biggest impact is that Heavenly Moon cards are now banned from tower content entirely. Players who relied on Moon cycle units to push tower floors need to rebuild their tower-specific teams from scratch.

This change forces more diverse compositions in tower content. Before this patch, a stacked Heavenly Moon lineup trivialized most tower floors. Now you're back to optimizing around the non-Heavenly card pool, which makes tier positioning for mid-range cards more relevant than it's been in months.

Quality-of-Life Improvements

• Skin selector replaces the old "Equip X Skin" buttons in the deck UI — cleaner and faster to navigate
• Effect lists on field cards are now scrollable, fixing the long-standing issue where cards with many effects had text overflow
• Inactive stat change chips now display with reduced opacity, making it easier to distinguish active buffs from expired ones at a glance
• Tutorial skip fix — skipping the tutorial now correctly removes the lingering boss guide overlay that previously stuck around

How This Affects Gameplay

The Demon Invasion mode reshapes how you spend your daily play sessions. Previously, world bosses were a timed event you'd participate in whenever they spawned. Now there's a persistent PvE loop you can grind at your own pace. That's a fundamental shift in how the endgame is structured.

The separate roster system means your main deck strength doesn't carry over. A player with a stacked Heavenly Moon lineup in the main game starts Demon Invasion on equal footing with everyone else. Your Knight pulls and upgrade decisions within the mode are what matter. This creates a fresh progression curve that rewards time investment over gacha luck from the main game.

Elemental matchups are the core of Demon Invasion team-building. With 4 elemental banners to recruit from, you want coverage across all elements rather than stacking a single type. Missions telegraph which demon elements you'll face, so you can tailor your team composition before each run.

The Battle Tower ban list change hits hard if you were coasting on Heavenly Moon cards. Re-evaluate your tower lineup using the current tier list. Cards in the A and S tiers that weren't seeing tower play are suddenly viable again. Eclipse-tier attackers and strong support cards move up in practical value for this content.

New Codes

Several codes dropped alongside Update 6.6. We maintain a full, regularly verified list on our Anime Card Clash codes page, but here are the ones tied to this update.

Redeem these from the codes menu in-game. The ANNIDELAY codes reference anniversary delays during development and stack with each other, so grab all three. Check the codes page for any new additions — developers often release extra codes in the days following a major update.

Updated Tips and Strategies

Getting Started with Demon Invasion

1. Use your free pull on each of the 4 elemental banners to start with elemental coverage
2. Focus on clearing the easiest missions first to build Yen reserves for more Knight pulls
3. Upgrade your best Knight to 3-star tier as quickly as possible for the first ability unlock
4. Expand your team slots before party slots — more cards per team matters more early on
5. Check the mission preview for demon elements and match your team's strengths against their weaknesses
6. Buy instant rolls from the Invasion Shop with your mission rewards to accelerate roster building

Adapting to the Tower Ban List

If your tower team relied on Heavenly Moon cards, start rebuilding now. Look at Eclipse-tier attackers with strong single-target damage — they've always been solid but were overshadowed by Moon units. Support cards with healing or shielding effects also become more valuable when you can't brute-force floors with raw Heavenly stats.

Check the Anime Card Clash tier list for current rankings. Cards in the A-tier with good tower synergies may outperform higher-rated cards that don't fit the new meta.

Prioritizing Your Pulls

With two new ultra-rare cards in the main gacha and Knight pulls in Demon Invasion competing for your resources, you need to decide where to focus. For most players, spending Yen on Demon Invasion Knight pulls will yield better returns than chasing the 1-in-12-billion odds on Commandment of Love or King of Chaos.

That said, if you've stockpiled Greater Moon Cycle Potions from the anniversary event, using them now gives you a shot at the new cards without diverting resources from Demon Invasion. The potions target the Heavenly pool specifically, which includes both new additions.

Community Reaction

The community response to Update 6.6 has been largely positive, with Demon Invasion drawing the most attention. Players who found the world boss system repetitive are welcoming the deeper progression mechanics. The separate roster design drew comparisons to how dungeons work, and most feedback has been favorable about having a fresh system to build from scratch.

The Battle Tower ban list change split opinions. Competitive tower climbers who invested heavily in Heavenly Moon cards feel the nerf was too aggressive, arguing that banning an entire tier removes build diversity rather than adding it. Others counter that Moon cards made tower content trivially easy and the ban list forces genuinely strategic team-building for the first time in months.

The new cards' drop rates generated the usual conversation. At 1 in 12.25 billion and 1 in 12.75 billion respectively, Commandment of Love and King of Chaos sit at the extreme end of the rarity spectrum. Most community discussion treats them as collector trophies rather than practical team additions, given that similar-stat cards are available at lower rarity tiers.

Quality-of-life fixes — especially the scrollable effect lists and the skin selector — earned quiet appreciation. These aren't flashy changes, but they address pain points that players have flagged since earlier updates.
