🗡️ Assassin Deck Guide — Shadow Realms

Playstyle: single-target burst66 cards in pool

Assassin decks are Shadow Realms' most unforgiving archetype — low HP, extreme ATK, and mechanics built entirely around killing one target instantly before it can respond. The signature mechanic is Shadowstrike: an opening hit that deals bonus damage based on the target's current HP, maximising burst against full-health opponents. Land a Shadowstrike, chain it into a standard attack, and most cards die before they've dealt a single hit back. Assassin decks are polarising: they demolish poorly-built defenses and fold to walls of HP or damage mitigation. The most competitive Assassin builds sacrifice deck consistency for maximising single-target burst, using Common Assassins as cannon fodder to trigger opponent abilities early before the high-rarity finishers land Shadowstrike from unexpected angles. Counter: Guardian and Angel decks have enough HP to survive Shadowstrike's burst window and heal or mitigate the follow-up. Construct Overdrive activates before Assassins can chain-kill. Assassin decks are high-skill, high-reward — brutal in the right hands, fragile in the wrong matchup.
