You may draw cards from anywhere in your library. (You don't get to look at them or reorder them while doing so.)
When Heart of a Duelist enters the battlefield, draw a card.

Heart of a Duelist

Instant

Multicleave {1} (You may pay an additional {1} any number of times as you cast this spell. For each time you do, choose a paired set of square brackets and remove the words in between.)
Destroy target [nonblack] creature [with mana value 3 or less] [an opponent controls]. You [and its controller each] draw a card [and lose 2 life]. Create a [tapped] 1/1 white Spirit creature token with flying.

Cleaver Blow

If an opponent would create one or more tokens, they create half that many of each of those kinds of tokens instead, rounded down.
If an opponent would put one or more counters on a permanent or player, they put half that many of each of those kinds of counters on that permanent or player instead, rounded down.

Whenever Pinchy McStingbutt deals combat damage to a player, conjure a card named Death of a Thousand Stings, Lethal Sting, or Stinging Shot at random into your hand and reveal it. (Treat conjured cards like cards.)

Pinchy McStingbutt

Enchantment Creature — Elemental Pirate

Reach
When Flavor Disaster enters the battlefield or when it's turned face up, target creature gets +X/+X until end of turn, where X is Flavor Disaster's power.
Negamorph {1}{G} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up any time for its negamorph cost and put a -1/-1 counter on it.)

Flavor Disaster

Creature — Phyrexian Plant

Phyrexian Seedling enters the battlefield with a +1/+1 counter on it.
Proliferatelink (Damage dealt by this creature also causes you to proliferate that many times. You proliferate before checking for lethal damage on creatures.)

Phyrexian Seedling

Retrace (Sorry, no room for reminder text.)
Choose one at random. Create a copy of the chosen card. You may cast the copy without paying its mana cost.

Legendary Creature — Plant Rogue

Each creature assigns combat damage equal to its mana value rather than its power.

Narod, the Beige Flower

Poly Artifact

{2}: Add one mana of any color.
Other noncreature artifacts are mono and continuous. (Each activated ability of mono artifacts costs an additional {T} to activate if its cost doesn't already include {T}. As long as a continuous artifact is tapped, it loses all abilities.)
