Caster CodexNo Standard, no Modern - just 100-card singleton. Find a commander, brew a bracket-aware 99, and ship a list you can actually play. No AI in the product: search, meta, and tools are deterministic features you control.
Search, organize, annotate, and playtest - without leaving the table.
Caster Codex does not use AI for these features. Meaning search, synergy suggestions, roles, notes, and play rooms are real product tools - not generated chat.
Live deck building that brings Scryfall-style function tags and EDHREC-informed builds together. Filter by what a card does, then pull high-synergy meta picks straight into the list without tab-hopping.
Multi-select cards and stamp Ramp, Draw, Removal, or Protection in one pass. Use global role tags that follow you across decks, or add a role to a single card with one click - bulk when you want speed, per-card when you want precision.
Keep mulligan lines, proxy plans, and playtest reminders on the deck - plus short notes on individual cards. Only you see them; never on public deck pages.
Spin up a live table, share a short room code, and draw from your list together. Perfect for testing lines before sleeve night.
From first commander to final cut - all without AI behind the scenes.
