Best Burst Assassin Deck Guide

One Shadowstrike. One dead card. Total dominance in the burst window.

Class: Assassin Playstyle: One Shadowstrike. One Cards: 20

Burst Assassin is 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. High skill ceiling, high reward.

Best for: High-skill players who want maximum damage in minimum time.

Mulligan & Game Plan

Mulligan Steps

  1. 1. Keep 1-2 low-cost Assassins (cost 1-3) to establish early board control.
  2. 2. Prioritise cards with Shadowstrike or guaranteed-hit burst — they define the identity.
  3. 3. Mulligan for fast opening. Hands with 2+ cost-5+ cards are too slow.
  4. 4. Dusk Shade is the best opener — keep it to set up Shadowstrike chains.

Game Plan

  1. 1. Play fast, low-cost Assassins on turns 1-3 to set up burst sequences.
  2. 2. Trade aggressively on turns 3-5 to clear the path for your finishers.
  3. 3. Deploy high-rarity Assassins on turns 5-7 and Shadowstrike key opponent targets.
  4. 4. In Arena, position Assassins to hit the opponent's damage carry first.
  5. 5. Counter: Guardian and Angel HP pools absorb Shadowstrike and outlast the burst.
