Usually safer
- Tracking your own deck and hand-visible information.
- Showing cards already played.
- Counting visible board damage.
- Post-game review and training drills.
Fair-play guide
Is Hearthstone Deck Tracker allowed?
The safer way to think about helper tools is simple: visible information and memory aids are different from automation. Tournaments can also set their own rules, so always check the event policy before using any overlay.
Riskier territory
- Automated clicks or game actions.
- Hidden-information inference shown as fact.
- Real-time instructions that replace player decisions.
- Claims that a tool is officially approved or ban-proof.
LethalCue's boundary
LethalCue should start as a training and review tool: deterministic visible damage, missed-lethal review, and puzzle practice. Keep the plugin conservative until the rules and community feedback are clear.
