MLB Showdown

Overview

MLB Showdown is a collectible card game by Wizards of the Coast that simulates baseball. Each player builds a team from player cards representing real MLB players, then plays a full baseball game. A 20-sided die determines outcomes, with results modified by player card stats for batting, pitching, and fielding. The game ran from 2000 to 2005.

Components

Setup

  1. Each player builds a team of player cards (following deck construction rules: a pitcher, lineup of 9 batters, bench players).
  2. Set up a score tracker for innings.
  3. Determine home and visiting teams.
  4. Each player selects their starting pitcher.

Turn Structure

The game follows baseball innings. Each half-inning:

  1. Pitching: The defending player uses their pitcher card.
  2. At-bat: The batting player sends batters up in lineup order.
  3. Resolution: Roll the d20. Compare to control number on the pitcher or batter card to determine which card’s chart is used. Then roll again on that chart for the result.
