Deck Tools
Overview
Analysis, testing and assembly tools built into every deck.
The tools live in the deck screen's two-tier deck bar, each in its place:
- Data tier → Value (what the deck is worth and which cards drive it), Insights (mana curve, color balance, health signals) and Bracket (the official Commander power-level brackets, Commander decks only).
- Tools tier → Playtest — goldfish the deck interactively; the Simulate hand lab opens from a tile inside Playtest — and Build sessions for assembling the paper deck.
- Ideas tier → the EDHREC recommendations (Legality & Ideas), Commander decks only.
- Legality isn't a tab at all: it's the chip in the deck header — tap it for the card-by-card breakdown.
What works on which deck
- Your decks — everything (Bracket, EDHREC and Staples require a Commander-format deck).
- Commander precons (read-only) — Playtest, Value and Insights work; Build, Notes, History, Bracket and Ideas are hidden until you clone it into a deck of your own.
- Secret Lair drops — Value and Insights only (a drop is a product, not a playable deck).
