Fractal: Only matters if you are drawing many cards per turn. Remember Fractal is not Drawing. Verdict: Undecided. Abuse not evident.
Overdrive: Reset to 0|14 each turn. That is 2|3 damage per turn. Verdict: UP
Gravity Pull: Is removed at the end of the turn. Verdict: Wasted
Suggestion: "Reset stats and remove statuses each turn."
However note that:
Reseting stats will already render Adrenaline useless (the 2nd attack is a 2nd creature turn thus is 0 atk)
Gravity Pull + Token Drake would be worse than healing 13hp per turn. It might not need excluding.
Note: adrenaline and gravity pull is passive
No. They are status effects. They are not skills. Not even passive skills.
