II · The Sieve

Sixteen ways to narrow a fate

Every sieve below can be laid over the others at once. Ask for one, ask for nine. What falls through is deduplicated by oracle identity, fifty at most.

III · The Weighing

Hand over your hundred

Paste a Commander list as it left your deckbuilder. The vault counts it, weighs every card against the format's laws, and tells you plainly what is wrong.

What the scales test

A hundred, counted
Commander asks for exactly one hundred cards, the commander among them.
One of each
Only basic lands may be doubled. Everything else is singleton.
A commander who may lead
Legendary, or bearing the line that says it can. Two only under Partner or a Background.
Nothing banned
Every card weighed against the Commander banned list.
Inside the colours
No card may carry a colour its commander's identity does not.
Game Changers, counted
How many you are carrying, and the lowest bracket that still allows them.
Lists it can read

Commander
1 Atraxa, Grand Unifier

Deck
1 Sol Ring
1x Cultivate (m21) 177
10 Forest

Sideboard
1 Nature's Claim

One card to a line, with or without the set and collector number. Section headers are understood — and sideboards, maybeboards and token piles are left out of the count, then named in the answer so you know what was set aside.

IV · The Eight Keys

A small ring, on purpose

Eight doors is all the vault has. Anything worth asking fits through one of them.

I
search-card
One card, called by its true name. The vault hands back its newest printing.
