Mecha Cube

Core damage skill with high base power, permanently +20 power each turn when position changes. Combined with [Blind Twist] that auto-shuffles position each turn, can theoretically trigger damage boost every turn—grows stronger over time. Best placed in slot 4 for -4 Energy cost (80→76), but even outside slot 4, works well with [Bearing Support] or [Lever Swap] for effective energy reduction.

Core position control skill, 0 energy cost, restores 2 energy and swaps adjacent skill positions. After [Blind Scramble] disrupts positioning, if key output skills are not in ideal positions, this skill can adjust them. Also restores energy to ensure sustain, the core lubricant for Mecha Square's skill cycle.

A powerful support skill with 0 energy cost; passive effect reduces adjacent skill energy costs by -1, active use grants additional -1. Coordinates with high-cost skills like 【Gear Torque】 to greatly reduce usage cost; 【Blind Twist】's slot 4 cost reduction + 【Bearing Support】's cost reduction can stack, enabling extremely low cost to unleash high-power skills

High-burst damage skill. 70 cost. At slot 1: +90 power and Transmission 2. Though [Blind Twist]'s random position makes it unstable, can manually adjust to slot 1 with [Lever Swap], or rely on [Blind Twist] randomly hitting slot 1 for burst. At slot 4 enjoys -4 cost (70→66), excellent damage alternative.

Core damage skill with 45 Energy. +60 power and Transmission 1 when in Slot 1. Low cost with high returns; extremely cost-effective when randomized to Slot 1 via [Blind Twist]. Even when not in Slot 1, the 45 Energy base output remains stable, making it a reliable choice for early-game transition and late-game cleanup.

Core Support skill. 0 energy cost. When in slot 1 or 3, gains +60% Physical Attack and Transmission 1. +80 Speed is crucial for Mechanical Cube with 51 Speed, can compensate for speed disadvantage to争取 first action. Physical Attack bonus combined with [Power Boost] can stack extremely high Physical Attack panel, core of burst preparation.

Core buff skill, 0 energy cost, directly grants +100% Physical Attack. When stacked with [Mesh Transmission]'s +60% Physical Attack, reaches terrifying 260% (1.6×2.0=3.2x base). 0 energy cost means it can be inserted into the rotation anytime without occupying damage turns, key to speed burst strategies.

High-burst damage skill. 65 cost. +55 power if a status skill was used last turn. [Engage Transmission] and [Power Boost] are both status skills. Using either enables [Counter Every Move] to trigger power boost next turn, forming standard 'buff→burst' combo. At slot 4 enjoys -4 cost (65→61), further improving value.

Core damage skill with 55 Energy, Priority +1. Mech Cube's 51 Speed is relatively slow; [First Strike]'s priority effect effectively counters opponents with similar or slightly higher Speed, securing turn priority. 55 Energy is moderate—placed in Slot 4 with -4 Energy reduction becomes only 51 Energy, offering excellent cost-performance.

Core buff skill, 0 energy cost, +100% Physical Attack. As an unrestricted powerful buff, it's the foundation for any physical attack build. 0 energy cost allows flexible insertion into any turn. Combined with [First Strike]'s priority trait, enables a safe "buff → priority attack" rhythm.

Core sustain skill, 0 Energy cost, recovers 25% HP, 50% when responding to Defense. Mech Cub has low 62 HP and is easily worn down without recovery means. [Stress Response] provides stable recovery, with doubled efficiency when anticipating opponent's Defense, improving survivability.

Core support skill with 0 energy cost. Passively reduces energy cost of adjacent skills, and actively reduces by an additional 1. In this build, [First Strike] costs 55 energy, [Power Boost] and [Stress Response] cost 0 energy. [Bearing Support] primarily serves to reduce [First Strike]'s energy cost (can be reduced below 50 when paired with [Blind Twist] in slot 4). The [Transmission 1] effect can also synergize with other skills' position mechanics.
