Build a game where you play cards from a hand against an enemy that shows what it will do

A card duel runs on a draw pile, a hand, a discard pile and a small supply of energy per turn. The classic slip is a draw pile that runs dry in the middle of drawing. Here is a loop that reshuffles at the right moment and keeps every card.

Why this works

A deck is a promise that every card will come back. Three piles, with a single place where drawing happens, mean no card is ever lost or doubled, and the player can plan around what is still to come.

When not to use it

Skip it for games where hidden luck frustrates, or where the player should always have every option open. Give a fixed set of moves each turn instead of a shuffled deck.
