Riftbound Secret Garden: the $70 event box now trades at $280

Secret Garden was never on a shop shelf. It was sold at Riftbound events this summer: a collector box built around Lillia and Ivern, $70 at the table, and a set of three numbered promos. Three months later the box trades at four times that, and the three promos are going three different ways.

All numbers come from TCGIndex's set and card pages (English, TCGplayer market price), read on November 3 and 4, 2026.

The box: $70 at events, $279.58 today

The Secret Garden Box has a price on our page since August 9, when it showed $232. The low came two days later, $221.54 on August 11. Then it climbed for five weeks, to a peak of $322.38 on September 17.

Since then it has given back a bit every week:

• September 17: $322.38 (peak)
• October 7: $305.74
• October 23: $289.01, the day Radiance came out
• November 3: $279.58, 13 % under the peak, 10 % down on 30 days

That is still 4.0 times the $70 event price. Anyone who walked out of an event with a sealed box and kept it is sitting on a real number. Anyone who bought one in mid-September paid the top.

Three promos, three directions

The set is three numbered cards, 001/003 to 003/003. Together they add up to $252.90 raw today, a little under the sealed box.

• Lillia, Bashful Bloom 001/003: $116.02. First price $88 on August 16, peak $127.85 on September 22. Down 9 % from the peak, still 32 % above where it started. The card of the set, and the one holding best.
• Ultrasoft Poro 003/003: $95.80. $100 on August 13, a dip to $91.50, then $126.52 on September 27. Today it is back under its first price, 24 % below the peak.
• Ivern, Green Father 002/003: $41.08 (November 1). Its first price, $69.95 on August 17, was also its highest. It has gone down almost every week since: $60.55, $54.11, $45.17. -41 % in eleven weeks.

So the same small set holds a card that went up, one that went round trip and one that lost two fifths. If you own all three, Lillia is the copy to look after.

Why the slide since September

Two forces. The first is the calendar: Vendetta was already out (July 31) and Radiance arrived on October 23. Every new set pulls players' money toward its own chase cards, and promos with no play role feel it first.

The other is plain supply. An event exclusive is scarce at first, then the boxes that people kept start coming out of closets. The box went up for five weeks and has eased for seven. That is a market finding its level, not a crash.

What we watch next

• Lillia under $110 would be the first sign the card of the set is following Ivern.
• The box under $250 would put the sealed box below the three promos bought loose ($252.90 today), where it last sat in mid-August.
• Legacy, January 29, 2027: the next Riftbound set. We will compare what Radiance, Vendetta and Secret Garden did from a month before release to a month after, and publish it 30 days out.
