The default experience is a post-game result card, not a live instruction panel.
HDT plugin guide
A Hearthstone Deck Tracker plugin for KO review
Deck trackers help you remember the game. LethalCue's job is narrower: after a match, it tells you whether a visible lethal chance appeared, how close your best turn was, and what kind of puzzle to practice next.
Visible state
The plugin should use public board state, known hand/deck information, and conservative damage rules.
Training loop
Each result should point the player to one useful practice theme: board damage, spell damage, taunt math, or sequencing.
Who should install it?
LethalCue is best for beginner, returning, and lower-rank players who often feel that a game was winnable but cannot quickly see where the lethal line was. Strong players may not need the plugin; the product is built for learning speed, not professional replay analysis.
