Team Trio Validator helps Magic: The Gathering players verify compliance with team constructed rules.
Paste three deck lists in plain text, e.g. 3 Lightning Bolt or 3x Lightning Bolt, using Sideboard to separate sections and instantly check for violations.
The tool supports the Unified deck construction format (ensuring no non-basic land card appears in more than one deck), and enforces per-deck limits (60 card minimum in main, 15 in side, 4 copies max per card).
