Draw four cards, then untap up to two target lands.

Draw X cards, then abound. (To abound, you may cast a spell that costs less than this from your hand without paying its mana cost.)

Pressure {B} (You may cast this spell for its pressure cost if seven or more cards are in your graveyard.)
Search your library for a card, put it into your graveyard, then shuffle. You gain 2 life.

Exile the top card of your library. You may play that card until the end of your next turn.

Whenever Burning Hart deals combat damage to a player, it deals that much damage to up to one target planeswalker that player controls.

Vanishing 3 (This permanent enters with three time counters on it. At the beginning of your upkeep, remove a time counter from it. When the last is removed, sacrifice it.)
Whenever a time counter is removed from Burning Heels, exile the top card of your library. Until end of turn, you may play that card.

Tithe (As you cast this spell, you may tap three artifacts and/or creatures you control.)
Any opponent may have you draw three cards. If they don't, Burning Revelations deals 5 damage to them. Then if you cast this spell and its tithe was paid, copy it twice.

You may cast this spell as though it had flash if it targets a creature or planeswalker.
Burning Up deals X damage to any target, where X is the number of basic land types among lands you control.

Whenever a player activates an ability that isn't a mana ability, Burning-Tree Shaman deals 1 damage to that player.

Bustling Marketplace can't be sacrificed.
{T}: Add one mana of any type that a land you control could produce.
{0}: Bustling Marketplace's owner may draw a card. If they do, untap Bustling Marketplace and gain control of it until end of turn. Only your opponents may activate this ability and only once each turn during their turn.

Deathtouch
Once each turn, you may cast a creature spell from your graveyard by paying life equal to its mana value rather than paying its mana cost.

Permanents you control with mana value 1 or less have first strike, haste, and lifelink.

Creatures you control get +0/+1 and can attack as though they didn't have defender.
Whenever three or more creatures you control attack or block, each creature you control assigns combat damage equal to its toughness rather than its power this turn.

Your life total becomes 0. Until an opponent's next turn, you can't lose the game, your opponents can't win the game, and you can't gain life.
Take an extra turn after this one.
Exile Buy Time.

Once each turn, when you spend mana from a Desert to cast a spell, create a 1/1 red and green Bird creature token with flying and vigilance.
Whenever three or more creatures you control deal combat damage to a player, untap each land you control.

Archive X (As this enters, shuffle the top X cards of your main library into a new face up library. Sacrifice this after the archived library is empty.)
Whenever you draw a card from the archived library, create two 1/1 green Insect creature tokens.

[+1]: Create a green enchantment token named Swarm with “At the beginning of your end step, create a 1/1 green Insect creature token.”
[–2]: Create a green enchantment token named Survive with “Whenever a creature you control dies, you gain life equal to its power.”
[–4]: Create a green enchantment token named Scrounge with “Whenever a creature you control enters, draw a card.”

Create a 1/1 blue Otter creature token with “Whenever this creature deals combat damage to a player, draw a card.”
Wanderlust — If you control four or more differently named lands, create two of those tokens instead.

({T}: Add {W}.)
Bygone Guardian enters tapped.
Vigilance
{2}{W}{W}: Bygone Guardian becomes a creature in addition to its other types until end of turn.

Whenever Bygone Wreck deals combat damage to a player, you may sacrifice it. If you do, create five Treasure tokens.
Crew 1 (Tap any number of creatures you control with total power 1 or greater: This Vehicle becomes an artifact creature until end of turn.)

Foretell {1}{G}{G} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)
Choose one. If this spell was foretold, you may choose both instead —
• Create two tapped 1/1 white Peasant creature tokens.
• You gain 7 life.

When Byron, Unlikely Hero enters, put a +1/+1 counter on each other Citizen or Peasant you control.
Whenever a nontoken creature you control with a +1/+1 counter on it dies, create a 1/1 white Peasant creature token.

Whenever Byway Bruiser enters or leaves the battlefield, you may have it deal 3 damage to any target.

When Cabinet of Curiosities enters, create a Vial token. (It's an artifact with “{1}, Sacrifice this and another permanent: Draw a card. Activate only during your turn.”)
If an effect would create one or more tokens under your control, it creates twice that many of those tokens instead.

Whenever one or more cards are put into an opponent's graveyard from their hand or library, Cackling Tormentor deals 2 damage to any target.
