How it works
Nothing magical. We just refuse to look away.
Pool composition, current asks, fresh pulls — every pack Arena Club lists. The market moves; we notice.
For each pack: probability-weighted payout minus price and fees, cross-referenced against recent public-marketplace sold results. Refreshed when the pool moves.
Open the watchlist before any rip — EV, pull odds, pool composition, plus the CS Trigger on Pro. The math, on demand.

Frequently asked
What is Collect Safe?
Arena Club's insurance add-on: pay 10% extra on a pack and they guarantee at least 80% of the pack price as a buyback on what you pull. Sometimes that's a great deal (deep, lumpy pools where most cards are well below 80%). Sometimes you're paying 10% for nothing (pools that mostly clear 80% on their own). Our CS Trigger shows the % of pulls where Collect Safe's floor actually kicks in, per pack — so you can decide. It's a Pro feature.
So you tell me what to buy?
No. We compile estimated card values ("comps") and compute the odds to estimate the EV. You make the decision. The CS Trigger (Pro) shows how often Arena Club's insurance add-on would pay out; it doesn't grade the pack itself.
What is "+EV"?
Positive expected value. The probability-weighted average payout of a pack exceeds its price, net of fees. It's a long-run average — any individual rip can still bust.
Can you track my pulls?
Yes — and it's free. Link your Arena Club handle and every pull we catch under your name shows up on your page: card value, where it ranked in its pool the moment you ripped, badges for your best hits. On Pro, Rip Mode checks the pack you're ripping about every ~30 seconds, so your pulls are caught as they happen. One catch: a card sold back to Arena Club before our next check won't be picked up — hold each pull until you see the hit. We'll also show you the estimated value of the card, based on our comping engine. Pro users in Rip Mode see this within seconds.
Why a 1-hour delay on free?
Markets move fast. Free accounts still get most of the picture — just on a 1-hour delay. Browsing logged out? Public pack pages show a 6-hour-delayed snapshot — a free account gets you the 1-hour view.
Are you affiliated with Arena Club?
No. We have no business relationship with Arena Club today — no affiliate program, no sponsorship, no data deal. If that ever changes, we'll disclose it here, prominently. A paid relationship will never change what our EV math or our CS Trigger numbers say.
Do you cover other marketplaces?
Not yet. Credit to Arena Club for publishing their full card pools — they're the reason a site like this can exist. Most marketplaces don't show you what's actually in a pack, which makes EV impossible to compute honestly. When another marketplace opens up the same way, we'll add it.
The numbers can flip without warning.
Free gets everything on a 1-hour delay. Pro gets the most recent readings with no added delay, plus Rip Mode while you rip — $19.99/mo, cancel anytime.
