Most impactful swaps
Chosen by fit: each add fills something your plan is short on, swapped against the piece your deck can best spare, then playtested for speed. The sections below hold plenty more ideas worth a look. Rate any swap with 👍/👎, or if something looks off, report it to help improve the site.
Cards to consider adding
Picked by reading card texts to fit your plan instead of just copying what's popular. Legal in your colors and bracket; click a card for prices.
Badges: Staple, Very common, Common and Niche say how widely a card is played on EDHREC. GC marks a Game Changer, which counts toward your bracket's limit. On a phone, tap any badge for its full explanation.

Playtest
Paired solo games on both versions of the deck, same shuffles, so the difference is the swap and nothing else.
What it can and can't see
These are solo playtests, what Magic players call goldfish games: your deck plays against nobody. They measure how fast and how consistently your deck does its thing. They can't tell you a win rate. No opponents, so removal, politics, and your table's meta don't show up. We count one-shot treasures and rituals. We don't count repeating treasure engines or cast-loop combos, so those look smaller here than they play. A card can be right for reasons no simulation can see. Treat all of this as evidence and make the call yourself.
