Magic is Ruby, Ruby is Magic!
summary
A Ruby app that simulates Magic The Gathering models the full game loop with actions → effects → events, implements the stack and triggered abilities, and encodes cards as a Ruby DSL; about 200 cards are implemented so far out of ~25,000, with roughly a million words of rules to model. Replacement effects are handled as a middleware-like chain, tests drive each card, some cards force rearchitecting, and infinite-action loops detection remains an open challenge. The project is on GitHub.
