How to use TurnZero HQ
Trading with people you play with every week is mostly a pricing problem wearing a social costume. Put both piles on the screen, price the exact printings involved, and let the numbers be the thing you argue with instead of each other.
Trading with strangers at an event is a negotiation. Trading with the four people you play with every Wednesday is something else: nobody wants to grind a friend, nobody wants to be the person who got ground, and the whole thing runs on both sides feeling like the numbers were roughly fair. The awkwardness is not about the cards. It is about neither person being sure what anything is worth.
Two phones with two price lookups open is the usual answer, and it is a bad one, because it is slow and because the two of you are almost certainly pricing different printings of the same card without noticing.
Trade setup puts your pile against theirs, totals each side, and shows how far apart the two figures are. That last number is the one the conversation is actually about, and having it on screen turns "is this fair?" into a question with an answer somebody can respond to.
Setup writes nothing. Not to your collection, not to theirs. You can build a trade, take it apart, try a different card on one side, and walk away from all of it, and the only trace is that you spent two minutes on it. The trade picker uses the same card search as the library's add sheet and the Deck Lab's add bar, so the controls are ones you already know from somewhere else in the app.
Where the other player permits it, you can look at their library first, which means a trade can start from what somebody actually has rather than from a vague memory of a binder. How My Library works →
A card is not a price. A card is a dozen printings with a dozen prices, and the foil showcase copy in somebody's binder is not worth what the set's ordinary printing is worth. TurnZero HQ carries every printing of a card, foil, showcase and borderless included, with what each is worth and which one you own.
For a trade that distinction is the whole ballgame. Both sides are valued against the copies actually changing hands, which removes the single most common way a friendly trade turns out lopsided after the fact.
Confirmation is a separate, deliberate step, and it is meant to be taken when the cards physically move. Only then do the two collections change. The reason to split it is that a large share of proposed trades never happen, and a tool that recorded intent as fact would leave both people's collections quietly wrong for months.
Confirmed trades go into a log, and every entry in it can be undone. Between those two things the record stays honest in both directions: what was agreed is recorded when it is real, what was mistyped can be taken back, and what never happened leaves nothing behind.
A card can be marked as printed rather than bought, in a deck or as copies in the collection, and a card marked that way is worth nothing everywhere the app counts money. That is the honest answer for a playgroup that proxies its expensive staples, and it is what keeps a collection value from being a fantasy figure. More on proxies in Commander →
In a trade it stops being a nicety and becomes the point. A total that quietly included proxies would be a number one person is trading against and the other person cannot honor.
Playgroups who trade with each other regularly and would rather not haggle
Anyone who has been burned by pricing the wrong printing of the right card
Players whose collection value has to stay honest, proxies included
People who want a record of trades that actually happened, and none of the ones that did not
No. Trade setup writes nothing. It values your pile against theirs and shows the gap, and nothing touches either collection until a separate confirmation step, which is the step you take once the cards have actually changed hands.
Because most proposed trades never happen. Somebody decides they want to keep the card, or the numbers do not work, and a tool that had already moved the cards would leave both collections wrong. Splitting the two means the half of trades that fall through leave no trace at all.
At the printing each side actually owns. Foil, showcase and borderless versions are all priced separately, so a trade is valued against the copy on the table rather than against whichever printing happens to be treated as representative.
Yes. Confirmed trades are kept in a log and each one is undoable, so a trade recorded against the wrong person or entered twice can be taken back off both collections.
A card marked as printed rather than bought is worth nothing, in a deck and in the library alike. That keeps a proxy-heavy collection honestly valued instead of inflating it, which matters most in exactly this context: nobody should ever be trading against a number that includes proxies.
Where they permit it, yes. Another player's library is viewable, so a trade can start from what somebody actually has rather than from two people guessing at each other's binders.
Both piles priced at the printings actually changing hands, and nothing recorded until the cards move. Free to start.
