When this creature enters, if you gained or lost life this turn, it seeks valor. (Give it that Oath Aura. Fulfill it by it dealing combat damage to a player to create a 2/1 white Soldier token.)

Put target land card from a graveyard onto the battlefield under your control.

Flying, haste
When Whisperwoods Phoenix dies or you discard it, create a red enchantment token named Ash with “Whenever you cast a noncreature spell, put a feather counter on this. Then if there are three or more feather counters on it, sacrifice it and return a card named Whisperwoods Phoenix from your graveyard to the battlefield.”

Choose one or both —
• Prevent all combat damage that would be dealt to creatures this turn.
• Detain target creature. (Until your next turn, that creature can't attack or block and its activated abilities can't be activated.)

Journey three times. (Exile the top three cards of your library face up. Whenever a creature you control deals combat damage to an opponent, put a journeyed card you own into your hand.)

Cadence (Whenever you cast a spell, if its mana value is greater than this creature's power, put a +1/+1 counter on this creature.)
Creatures with power less than Olten Survivalist's power can't block creatures you control.

When Memento Gorgon enters, mill X cards, where X is your devotion to black. Then return a card milled this way to your hand. You lose 1 life. (Each {B} in the mana costs of permanents you control counts toward your devotion to black.)

First strike
Other Foxes you control get +1/+1.
Whenever a Fox you control becomes blocked, it deals 1 damage to each creature blocking it.

(Transform this if it's not attached to a creature. Pay {3}{B} as a sorcery to unattach it.)
Enchant creature you control
Corrupted Mount's rider gets +5/+4 and can't block.

Each instant and sorcery card you own that isn't on the battlefield has inscribe. The inscribe cost is equal to its mana cost. (Exile that spell card inscribed on a creature you control. Whenever that creature attacks, its controller may cast a copy of the inscribed card without paying its mana cost. Inscribe only as a sorcery.)

Destroy target artifact or nonbasic land. Its controller creates a colorless artifact token named Lotus Petal with “{T}, Sacrifice this artifact: Add one mana of any color.”

When Anointed General enters, if you control a legendary creature, Anointed General deals 4 damage to target creature you don't control.

{1}{B}, Sacrifice another creature: Put a +1/+1 counter on Voracious Ghoul.

At the beginning of combat on your turn, choose a permanent type at random. Each player sacrifices a permanent of the chosen type other than this enchantment. If no permanents were sacrificed this way, sacrifice this enchantment and create a 6/6 black and red Rat Mutant creature token with trample and haste.

When Frontline Veteran enters, you may sacrifice another creature or artifact. If you do, draw a card.

Whenever you make first contact, Entelan Idealist gets +2/+2 until end of turn. (You make first contact the first time each turn you cast a spell with a name not in your graveyard or control already.)

Exile up to three instant or sorcery cards from your graveyard. You may cast a copy of each card exiled this way without paying its mana cost.

{T}: Target player mills a card.
{2}, Sacrifice Gilded Cipher: Draw a card.

Target opponent exiles a card from their hand. If this spell was cast from a graveyard, instead look at that player's hand, you choose a nonland card from it, then exile that card.
Flashback {2}{B} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Haste
Whenever Tunnel Moles attacks, you may have it phase out. (Treat it and anything attached to it as though they don't exist until its controller's next turn.)
Whenever Tunnel Moles phases in, it gets +2/+2 until end of turn and can't be blocked by creatures with flying this turn.

When Helvault, Shard of the Moon enters, for each player, exile up to one other target nonland permanent that player controls until Helvault, Shard of the Moon leaves the battlefield. When you exile a permanent you control this way, draw three cards.
{T}: Add {C}{C}{C}{C}{C}.
Cycling {2} ({2}, Discard this card: Draw a card.)

Reach, trample
When Anran, Root Steward enters, destroy up to three target noncreature permanents. For each permanent destroyed this way, its controller creates a colorless enchantment land token named Paradise with hexproof and “{T}: Add one mana of any color.”

Target player mills four cards.
Dominance — That player mills eight cards instead if you control the creature with the greatest power or tied for the greatest power.

Spells with mana value 2 or less cost {1} more to cast.
Spells with mana value 4 or greater cost {1} less to cast.

Tap up to two target creatures.
Flashback {3}{W/U} (You may cast this card from your graveyard for its flashback cost. Then exile it.)
