At the beginning of your upkeep, look at the top four cards of your library. You may reveal a storied card from among them and put it into your hand. Put the rest on the bottom of your library in any order. (Enchantment and legendary cards are storied.)

As an additional cost to cast this spell, tap three untapped creatures you control with power 1 or less.
Search your library for a creature card, put it onto the battlefield, then shuffle.

Haste
When Greenwood Outrider enters, creatures you control gain trample and get +X/+X until end of turn, where X is the number of storied permanents you control. (Enchantments and legendary permanents are storied.)

Put target artifact or enchantment with mana value less than or equal to the number of basic lands you control on the bottom of its owner's library.

When Meadow Songstress enters, conjure three cards named Meadow Songstress and shuffle them into your main library.
Whenever a nontoken creature you control enters, if it shares a name with one or more other creatures you control, draw a card.

When Ol' Sycamore enters, choose up to two —
• Ol' Sycamore fights another target legendary creature.
• Destroy target noncreature storied permanent. (Enchantments and legendary permanents are storied.)

Trample
Players can't activate abilities of nonbasic, noncreature permanents.

Your opponents play with their hands revealed.
Whenever you cast a spell with the same name as a card in an opponent's hand, draw two cards.

At the beginning of your upkeep, reveal the top two cards of your library. An opponent chooses one. Put the chosen card into your hand and exile the other.
{4}, {T}: Put a card exiled with The Knowledge Hub into its owner's hand.

{5}, {T}, Sacrifice Voidlife Orbs: Destroy all nonland permanents. You can't spend more than one color of mana to activate this ability.

Crystal Garden enters tapped.
{T}: Add one mana of any color. You can't spend this mana to cast a creature spell.

{T}: Add {C}.
{7}, {T}: Copy target instant or sorcery spell with {X} in its mana cost. You may choose new targets for the copy. This ability costs {1} less to activate for each instant and sorcery card in your graveyard.

Flying
Whenever Acabo, the Fabled Falcon attacks, you choose how up to one target creature an opponent controls blocks this turn.

At the beginning of your upkeep, create an Idol token. (It's an artifact with “{1}, Sacrifice this artifact: Put a +1/+1 counter on target creature. Activate only as a sorcery.”)
{5}{W}{W}, Sacrifice three Idols: Return target creature card from your graveyard to the battlefield with three +1/+1 counters on it.

The next time target creature would be dealt damage this turn, prevent all but 1 of that damage. Whenever that creature perseveres this turn, put a +1/+1 counter on it. (A creature perseveres when it survives damage.)

Vigilance
Whenever Cai Lan, the Chained perseveres, exile target creature an opponent controls until Cai Lan leaves the battlefield. (A creature perseveres when it survives damage.)

Flying
Whenever Circumspect Flock perseveres, create a 1/1 white Bird creature token with flying. (A creature perseveres when it survives damage.)
