What does Legion of the Dead do?

It is a 7-mana Legendary spell: it fills your board with Zombies (2⚔️/2❤️). One card, every free space taken.

What is the Golden Egg and Boogeyman combo?

Boogeyman is a 4-mana 7/7 whose On Reveal destroys the ally in its location with the lowest Power, even itself. Golden Egg is a 0/1 that summons a 5/5 Golden Goose on its space when it dies: put the Egg down first, and Boogeyman's ability turns it into a Goose instead of killing your own body.

What do you keep in the mulligan?

Bagheera and Thumbelina, ideally alongside Bullseye. The Golden Egg plus Boogeyman pair is worth keeping in the opening hand too.

Why is Mind Palace important?

The deck empties its hand quickly: without the two cards Mind Palace draws, you run out of plays before the Legendary lands.

Trick-or-Treat Legion: Origins TCG deck

The deck in one paragraph

The Trick-or-Treat Legion is an evil list led by Legion of the Dead, published on OriginsMeta on 22 September 2026 by Davdas, a member of the site's staff, and tagged for ladder, competitive and tournament play. Several versions of the Legion deck are going around; this one, in the author's words, wants to raise its unpredictability, putting together cards that "play a trick" on the opponent's board every round. The full list and the charts are on the deck page.

The list

Twenty-five cards: the Legendary plus twelve cards played as two copies each.

Card	Cost	What it does
Legion of the Dead (Legendary)	7	Legendary spell: fill your board with Zombies (2⚔️/2❤️)
Bullseye	1	Spell: 3 damage to ANY character
Bagheera	1	1/1; On Reveal on a middle space it gets +2⚔️/+2❤️
Thumbelina	1	2/2, no ability
Morgiana	2	2/3; prevents ALL On Reveal abilities from happening in its location
Mind Palace	2	Spell: draw 2 cards
Asanbosam	3	5/5; On Reveal discards a random even-cost card
Golden Egg	3	0/1; On Death it summons a Golden Goose (5/5) on its space
Flying Monkey	3	4/1; On Reveal moves ANY other character to a random space here
En Passant	3	Spell: move an ally and deal its Power to the character across from it
Boogeyman	4	7/7; On Reveal destroys the ally here with the lowest Power, even itself
White Queen	4	3/3; On Reveal returns ANY character to its owner's hand
Impundulu	5	3/6; when it attacks it adds a Lightning Strike to your hand, discarded before combat next round

Ten units and three spells. The three cheap cards are not filler: this deck needs the board to be its own before the Legendary arrives, because the Zombies only fill free spaces.

How the deck wins

Three cards do the damage — Boogeyman, Asanbosam and Impundulu — and everything else exists to protect them or open the way.

Boogeyman is a 7/7 for four mana, which is the best rate in the list, with a catch: on reveal it destroys the ally in its location with the lowest Power, itself included. Put it in an empty lane and it kills itself; put it next to a Golden Egg and the Egg dies, leaving a 5/5 Golden Goose on its space. That is the combo the author points at: two cards, a 7/7 and a 5/5.
Asanbosam is a 5/5 for three, and it makes the opponent discard a random even-cost card on reveal.
Impundulu turns every attack into a Lightning Strike in your hand: repeatable damage, as long as you spend it before the next combat.

The Legendary closes the game rather than starting it: at seven mana, Fill your board with Zombies takes every free space at once. It is at its best the round after a trade has emptied your side, or into the two locations you were not contesting.

The "tricks"

En Passant, Flying Monkey and White Queen are what the author means by playing a trick every round.

En Passant moves an ally and deals its Power to the character across from it: on Boogeyman or a Golden Goose it is five to seven damage that also repositions.
Flying Monkey moves ANY other character to a random space in its location: it drags an enemy blocker out of the lane, or brings your own body where the fight is. The space is random, so it is a trick, not a plan.
White Queen returns ANY character to its owner's hand: an enemy finisher goes away for a round, or your own Golden Egg comes back to be replayed next to a second Boogeyman.

Morgiana is the quiet one: in her location no On Reveal happens at all, for either side. Play her where the opponent's On Reveals hurt most — but remember she stops yours too, including Boogeyman's.

Mulligan

The author's note is short and clear: Bagheera and Thumbelina are perfect starts alongside Bullseye, and Golden Egg plus Boogeyman can decide the game even from the opening hand. Bagheera on a middle space is a 3/3 for one mana; Thumbelina is a plain 2/2, which at one mana is board presence you do not have to think about.

Round by round

Rounds 1–2: take space cheaply. Bagheera in the middle, Thumbelina wherever you expect to fight, Bullseye on anything with three Health.
Round 3: the first threat. Asanbosam as a 5/5, or the Golden Egg in the lane where Boogeyman is going next round.
Round 4: Boogeyman. Into the Egg if you have it, otherwise next to the smallest body you can afford to lose — and never into an empty lane.
Rounds 5–6: pressure and cards. Impundulu starts producing Strikes; Mind Palace refills the hand. The author is explicit about it: without Mind Palace the deck runs out of cards too early.
Round 7: Legion of the Dead. Every free space becomes a 2/2. Count the spaces before you play it: after a round where you traded a lot it is worth two or three bodies more.

Matchups

Ranked data is not public, so this is OriginsMeta's reading of the lists.

Against go-wide decks. The Zombies arrive on free spaces, so the wider the opponent is, the less the Legendary does for you. Use Bullseye and Boogeyman to open the board first, and keep Flying Monkey for the buffed body.
Against control decks. Asanbosam's discard and Impundulu's Strikes are the pressure that does not depend on the board surviving. Hold one Boogeyman back after a wipe: a 7/7 for four is the fastest way to rebuild.
Against On Reveal decks (for example On Reveal Mid Range, which repeats every On Reveal with Mulan). This is where Morgiana earns her place: put her in the location where they are stacking abilities, accept that your own On Reveals stop there too, and fight the other two lanes normally.

The weaknesses, in the author's words

Two, from the deck page: Mind Palace is very important, so you do not run out of cards too early, and Boogeyman needs a valid target, or Morgiana. The second is worth repeating: the 7/7 body is only good if something else in that location has less Power. The Golden Egg is the cheapest insurance, the Zombies from the Legendary are the late-game one.

Where to go next
