Epic Relics
Players disagree about Jack's overall design. Some consider his combo-heavy, off-turn kill playstyle highly rewarding and engaging. While others find his mechanics slow, clunky, and overly reliant on specific encounters, noting that his Focus-speed coin generation severely limits reactive plays and his damage is easily negated by the Tough keyword.
Infinite Rally Engine
Allows Jack to attack safely and utilize Prize Fight without taking lethal damage during combat.
Used to copy followers that grant Rally effects, creating a loop of continuous attacks.
Ensures Jack scales large enough to finish the game during repeated combat phases.
Strategy
This setup focuses on generating repeated attack phases to overwhelm the opponent. Death's Foil allows Jack to attack safely and utilize Prize Fight without the risk of dying in combat.
Condenser is utilized to copy specific followers that grant Rally effects when played, allowing for multiple attack tokens in a single round. Chosen by the Stars ensures Jack's stats scale high enough through the Fated keyword to push lethal damage through enemy blockers during these repeated combat phases.
Fated Brawler
- Provides Overwhelm and scales stats through the Fated keyword whenever Jack is targeted by Prize Fight or Coins.
Ensures a steady flow of spell mana to keep the combo engine running and triggers his star powers consistently.
Synergizes perfectly with Prize Fight, granting substantial stat increases when Jack takes non-lethal damage.
Strategy
This build maximizes Jack's combat scaling and mana generation. Chosen by the Stars provides essential Overwhelm and scales his stats rapidly through the Fated keyword whenever he is targeted by his generated spells.
The Berserker's Buckle compounds this growth, granting substantial stat increases every time he survives the damage from Prize Fight. Hidden Tome fuels this engine, ensuring enough spell mana is available to sequence multiple plays in a single round.
Mortal Marks Challenger
Grants Tough, significantly increasing Jack's survivability against the 'Mortal Marks' rule and general combat.
Copies spells played when 6+ mana gems are available, useful for duplicating Coins or other utility spells.- Grants +2|+2 to Jack when he survives damage, allowing him to grow continuously.
Strategy
This specialized build is designed to counter difficult encounters featuring the 'Mortal Marks' mutator (which sets all units' health to one). Armordillo Shell provides the Tough keyword, ensuring Jack survives the initial health reduction and subsequent pings.
The Berserker's Buckle allows Jack to scale his stats rapidly every time he survives combat or self-inflicted damage. Once you reach 6 mana, Chemtech Duplicator doubles your Coin generation and utility spells, providing overwhelming resource advantage to close out the game.
Sustained Control
Offers consistent access to his champion spell, providing removal and additional copies of Jack to maintain board presence.
Solves Jack's inherent card draw issues, ensuring a constant stream of resources.- Provides necessary combat scaling through Prize Fight.
Strategy
Jack frequently burns through his hand due to his low-cost spells and coin generation. The Gravedigger's Spade addresses this critical weakness by providing consistent card draw every round.
The Grand General's Counterplan ensures you always have access to Jack's champion spell for board control and combo generation. The Berserker's Buckle handles his combat scaling, turning Prize Fight into a consistent buffing tool to keep him relevant in the late game.
Other Relic Options
- Doubles all spells and coins once the game reaches 6 mana, creating massive board swings.
Provides a powerful Rally effect and Spellshield, synergizing exceptionally well with his combat-focused gameplan and self-damage mechanics.
Grants massive stat boosts that synergize with his mana refill mechanics and Overwhelm access.
Avoid Champion's Purse (Sett's signature relic). Jack's signature spell reduces units to 1 HP rather than killing them, meaning it will not trigger the relic's slay effect. Archangel's Staff is also considered suboptimal, as it only triggers a single 1-damage ping at round start, which is less efficient than sequencing Attune units. Guinsoo's Rageblade is ineffective because it requires the attack token to gain an item, failing to activate Prize Fight on Round 2.
Constellation
Jack's base star powers revolve around refilling spell mana to deal incremental damage to the enemy board. This mechanic requires careful sequencing and a steady supply of cheap spells or Attune units to function effectively. A major structural criticism is that his mana refill power provides no benefit if mana is already full, which can lead to awkward sequencing and wasted resources.
Tip the Scales
When you refill mana, give allies +1|+0 this round.
Sleepin with the Fishes
+1 Starting Mana. When you gain the attack token, create a Fleeting Prize Fight in hand.Review
Grants 'Prize Fight' to help set up kills and trigger self-damage synergies. However, it only generates on attack turns, which limits his defensive utility and reactive capabilities.
Tip the Scales II
When you refill mana, give allies +1|+0 this round and deal 1 to all enemies.Review
Deals 1 damage to all enemies when spell mana is refilled. This is highly effective against 1-HP mutators and wide boards, but it is completely negated by the Tough keyword, making certain encounters exceptionally difficult.
Gameplay Tips
- Beware the Tough Keyword
Jack's primary damage engine relies on 1-damage pings from his star powers and the Brash keyword. Enemies with Tough completely negate this damage, making encounters like Tryndamere or Lissandra exceptionally difficult. Avoid these paths when possible.
- Prioritize Card Draw
Jack's deck generates a massive amount of mana and cheap spells, leading to rapid hand depletion. Always prioritize drafting card draw powers or items during an adventure to maintain momentum and prevent stalling out.
- Leverage One-Health Mutators
Jack excels in Monthly Challenges or adventures featuring the "Mortal Marks" mutator (all units have 1 health). His consistent 1-damage pings will repeatedly wipe the enemy board, turning a difficult modifier into a significant advantage.
- Plan Around Focus Speed Coins
Because Jack's Coins operate at Focus speed, they cannot be used reactively during combat or in response to enemy spells. Plan mana usage carefully before committing to an attack, as you will not be able to generate burst mana mid-combat.
- Draft Pursuit of Progress
The "Pursuit of Progress" power is exceptionally strong on Jack. It grants attack buffs whenever units or Attune cards are played, perfectly complementing his mana-refill sequencing and turning his small units into significant threats.
- Sequence Attune Units Carefully
To maximize the effectiveness of Jack's 3-star power, wait for the opponent to develop their board before playing units with Attune. This ensures your spell mana refill triggers a board-wide damage ping that hits as many enemy units as possible.
