The Project
About InResponse
We are building a smarter way to brew Commander decks: one that understands the difference between what a card says and what a card does.

The Problem
Traditional search misses the point
Every Commander player has been there: you're refining your deck, cutting cards that don't quite fit, and you need a replacement. Maybe something cheaper. Maybe something faster. Maybe just something different that fills the same role.
Existing databases are incredible at answering rules questions and showing you what's in a color. But they fall short when you ask: "What plays like this card?"
A card that draws three cards and a card that lets you tutor for an answer are both "card advantage," but they solve very different problems. Traditional search can't capture these nuances.
Example
Searching for "Ramp"
✗
Keyword search returns:
Cards with "ramp" in the name or rules text
✓
InResponse returns:
All cards that accelerate your mana: mana dorks, rocks, land fetch, cost reduction, and more
Our Approach
Function over form
InResponse was built to answer the question "What plays like this?" not through keywords or card types, but through actual gameplay function.
Traditional Search
Text-based matching
- Searches for keywords in card text
- Returns exact text matches
- Misses functional equivalents
- No understanding of gameplay role
- Limited to what you can name
Better
InResponse
Function-based matching
- Groups cards by gameplay role
- Returns functional alternatives
- Captures nuanced differences
- Understands Commander context
- Finds cards you didn't know existed
The Vision
Picking the right piece, right when you need it
Commander is all about timing: the instant that saves the table, the silver bullet that keeps your strategy online, the pivot when plans change. InResponse is designed to hand you that exact piece of cardboard when it matters.
We look past card text and focus on intent, so finding the next best option feels as natural as drawing it from your sleeve.
The Philosophy
Our principles
The guiding philosophy behind our design.
Functional
Cards matched by role, not keywords. What a card does matters more than what it says.
Budget-Aware
Find alternatives at any price point. Great decks shouldn't require great wealth.
Multiplayer
Built specifically for Commander. We understand multiplayer dynamics.
Drag to Build
Seamlessly drag cards to Moxfield or Archidekt. Keep your brewing momentum.
Why InResponse
How we're different
What sets InResponse apart from every other card database.
Role-Based Classification
Every card is categorized by what it actually does in gameplay, not just what it says in the rules text.
Commander-First Design
Built from the ground up for multiplayer Commander, not adapted from 1v1 formats.
Budget Intelligence
Find functional alternatives at any price point without sacrificing gameplay effectiveness.
Contextual Understanding
We understand that a board wipe at 2 mana is fundamentally different from one at 7 mana.
Instant Comparisons
See how cards compare across speed, flexibility, and cost at a glance.
Brewer-Focused Workflow
Designed for the deckbuilding process, not just card lookup.
