Vigilance
When Worn Peacekeeper dies, create a 1/1 white Soldier creature token with vigilance.

Ferocious — At the beginning of each combat, if you control a creature with power 4 or greater, Worshipper Whelp gets +2/+0 until end of turn.

At the beginning of your end step, if you cast no spells this turn, you may return Wrathful Meditant to its owner's hand.

Whenever a nontoken creature you control enters, if it wasn't cast, put a +1/+1 counter on Wretched Skulker.
{3}{W}, Sacrifice Wretched Skulker: Exile target nonland permanent with mana value less than Wretched Skulker's power.

You may play an additional land each turn.
Whenever a player plays a land, that player draws a card.

{1}, {T}, Sacrifice two or more nonland permanents: Return target creature card from your graveyard to the battlefield. If permanents with total mana value 4 or greater were sacrificed this way, draw a card.

Flying
Whenever Yawning Crane deals combat damage to an opponent, target tapped creature that player controls doesn't untap during its controller's next untap step.

{T}, Sacrifice another creature: Return target creature card with mana value equal to 1 plus the sacrificed creature's mana value from your graveyard to the battlefield. Activate only as a sorcery.

Vigilance
{X}{G}, {T}: Ylda, the Wild Soul becomes a copy of target creature you control with mana value X, except it has this ability and vigilance. Activate only as a sorcery.

{T}, Pay 1 life: Add one mana of any color.

Flying
First strike (This creature deals combat damage before creatures without first strike.)
Lifelink (Damage dealt by this creature also causes you to gain that much life.)

Flying (This creature can't be blocked except by creatures with flying or reach.)
When Young Tempter enters, you draw a card and you lose 1 life.

Double strike, haste

Soldiercycling {2}{W} ({2}{W}, Discard this card: Search your library for a Soldier card, reveal it, and put it into your hand, then shuffle.)

Flying, vigilance
If a nonland permanent entering the battlefield would cause a triggered ability of a permanent you control to trigger, you may have that ability trigger an additional time. If you do, each opponent copies that ability and may choose new targets for the copies.

Flying
When Yujei enters, create a 1/1 white Bird creature token with flying.
{2}{W}: Put a +1/+1 counter on another target creature. It gains flying until end of turn. If it already has flying, put a +1/+1 counter on Yujei instead.

Whenever you cast a noncreature spell, look at the top X cards of your library, where X is that spell's mana value. Put those cards on top of your library in any order.

{2}{B}, Sacrifice a Clue: Target creature gets -3/-3 until end of turn.

{T}: Add {C}.
{T}, Sacrifice a creature: Add one mana of any color.

Deathtouch

Whenever another creature you control leaves the battlefield, put a +1/+1 counter on Zealot of Mahara.
Surpass {5}{W} ({5}{W}: Transform this creature. This costs {1} less to activate for each counter on it. Activate only as a sorcery.)

Trample
Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)

Zealous Rabble gets +1/+1 for each creature token you control.
At the beginning of your end step, if you're horrific, create a token that's a copy of Zealous Rabble, except it doesn't have this ability. (You're horrific as long as you've sacrificed a permanent or discarded a card this turn.)

Spirited (When this creature enters, you may activate one of its activated abilities without paying its cost.)
{G}: Zen Ascendant becomes a copy of a creature token you control until end of turn. (It's not a token.)

Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)
{T}: Add {G}.
