How we work out the good sell price for Sludge Monster
Every price on this page comes from CardKingdom’s buylist, which is what they pay to buy a card from you. We look at the last 90 days of that buylist for Sludge Monster and only count the times CardKingdom was actually buying it, because a price they are not buying at is not a price you could ever get.
We weight each price by how long it stayed in place. A price that held for three weeks tells you far more than one that lasted an hour, so the steady levels matter more than brief spikes.
From that history we work out three numbers for Sludge Monster:
- Normal ($1.23). The price the buylist sits at most of the time.
- Good ($1.23). A strong price that comes up often enough to be worth waiting for. It sits near the top of the realistic range with one off spikes stripped out, so it is a target you can expect to reach again rather than a fluke.
- Best ($1.23). The highest CardKingdom has paid for Sludge Monster while buying it in this period.
Because there is only a short history for Sludge Monster so far, we use the highest price seen as the good target until more data builds up.
We mark Sludge Monster as a sell once the current buylist reaches its good price, give or take a few percent, and as a hold below that.
What the numbers mean
- Current buylist. What CardKingdom pays for Sludge Monster right now.
- Wanted. How many copies CardKingdom is buying at that price. Zero means they have paused buying for the moment.
- Retail (NM). What CardKingdom charges to sell you a near mint copy. We show it for context, but our signals are about selling, so the buylist is what we focus on.
