Ward {1}
Streetslipper can't be blocked.
Whenever you foretell a card or cast a foretold spell, put a +1/+1 counter on Streetslipper.

You have hexproof.
Creatures you don't control have base power and toughness 1/1 and lose all abilities.
Nonbasic lands you don't control don't untap during their controller's untap step.

Trample
Ser Malcomn's power and toughness are each equal to the number of nonbasic lands your opponents control.

Whenever Poised Koi attacks or blocks, look at the top two cards of your library, put any of them into your graveyard, then the rest back on top in any order.

{T}: Add one mana of any color.

Flying, haste
{1}{R}{R}: Return Bloodfire Phoenix from your graveyard to the battlefield. Activate only if an opponent lost 3 or more life this turn.

When Frostfield Swordsman enters, arm it. (Create a colorless Equipment artifact token with “Equipped creature gets +1/+0” and equip {2}, then attach it to that creature.)

When Goldengrain Alseid enters, you may search your library for a basic Plains card, reveal it, put it into your hand, then shuffle.

3 | You gain 3 life.

Lifelink
When Sunlight Dancer enters, target opponent gains 4 life.

Flash
When Ancestral Warlord enters, it deals 1 damage to each blocking creature.

This spell costs {2} less to cast if an opponent was dealt combat damage this turn.
When Dastardly Duo enters, audition for black. (Create a 1/1 Construct Actor creature token, a Cleric Role giving 2/2 and lifelink, or a Warlock Role giving 2/1 and flying. Roles replace older ones.)

As Wayward Wanderers enters, you may have it become X/X with ward {X} and “Other creatures you control have base power and toughness X/X.”
{1}{G}: Return Wayward Wanderers to its owner's hand.

Target creature gets +3/-1 until end of turn.
Metamorph {1}{B} (You may cast this card face down as a 2/2 creature for {3}. Turn it face up and cast it at any time for its metamorph cost.)

Coastal Cairn enters tapped. When it enters, surveil 1. (Look at the top card of your library. You may put it into your graveyard.)
{T}: Add {U} or {R}.

Augmented — When TD-3 Slyten Retriever enters, if it's not a token and you've spent {W}{U}{B}{R}{G} to cast spells this turn, create a token that's a copy of it.
When TD-3 Slyten Retriever dies, draw a card and gain 3 life.

Lieshi Shrine enters tapped.
{T}: Add {W} or {B}.
{W/B}, {T}, Sacrifice Lieshi Shrine: Put a +1/+1 counter on target creature you control. Activate only as a sorcery.

Dead-Set Duo can't block.
Whenever Dead-Set Duo deals combat damage to a player, you may pay {B} and sacrifice it. If you do, they discard two cards.

Whenever Karoa, His Roaring Grace deals combat damage to a player, if he's not equipped, create a colorless Equipment artifact token named Banner attached to him. The token has equip {1} and “Equipped creature gets +1/+1.”

Noncreature spells you cast cost {1} less to cast.

Choose two —
• The next time a triggered ability of a permanent you control would trigger this turn, that ability triggers an additional time.
• Create a token that's a copy of a creature you control.
• Search your library for a creature card with mana value 2 or less, put it onto the battlefield, then shuffle.
• Sacrifice a creature. If you do, draw two cards.

When Mystic Seer enters, each player may scry 1.
{2}{U}: Draw a card, then discard a card.

Improve {1}{B/R} ({1}{B/R}: Put a +1/+1 counter on this creature. This costs {1} more to activate for each +1/+1 counter on it. Improve only as a sorcery.)
At the beginning of each player's combat, you may have that player create two goaded 1/1 red Goblin creature tokens with haste. Exile those tokens at end of combat. (Until your next turn, they attack each combat if able and attack a player other than you if able.)

Deathtouch
At the beginning of your end step, create a 1/1 black Rat creature token with “This creature can't block.”
{1}{B}, {T}, Sacrifice three other creatures: Each opponent discards a card and loses 2 life. You draw a card and gain 2 life.
