Gestalt (When this or another creature enters under your control, you may merge it with the one in play, keeping counters and attachments. They become the permanent on top plus all abilities from under it.)
If this creature would die, you may instead put a card or token merged with it into its owner's graveyard. If you do, remove all damage marked on this creature.

Whenever one or more creatures attack you or a planeswalker you control, reveal the top card of your library, then put a -1/-1 counter on each attacking creature with the same mana value as the revealed card.

{T}: Add {G}. Spend this mana only to cast a creature spell or activate an ability of a creature.
At the beginning of combat on your turn, if you control a creature with power 4 or greater, Vassal of the Wild gets +2/+1 and gains vigilance until end of turn.

{T}, Pay 1 life: Add {W}.
{T}, Pay 1 life, Sacrifice Vast Savannah: Search your library for a Plains card, put it onto the battlefield tapped, then shuffle.

Create an X/X green Mutant creature token, where X is the greatest power among creatures you've controlled this turn. If you control a creature with flying, the token has flying. The same is true for first strike, double strike, deathtouch, hexproof, haste, indestructible, lifelink, menace, reach, trample, and vigilance.

Whenever another artifact is put into your graveyard from the battlefield, each opponent loses 1 life and you gain 1 life.

Ve'aja, the First Bloodline's power is equal to the number of Clerics you control.
Whenever another nontoken creature you control dies, you lose X life and create X 1/1 black Cleric creature tokens, where X is that creature's power.

Whenever Vedlinn Ross becomes tapped, exile a nonland card from target opponent's graveyard. Copy it. You may cast the copy this turn. (You still pay its costs, including color. Copies of permanents enter as tokens.)
Whenever you cast a spell from anywhere other than your hand, copy it. You may choose new targets for the copies.

Once each turn, when Vedu, the Deepdrinker enters or you attack with one or more Horrors, you may tap up to two target permanents. If Vedu isn't a token, put two stun counters on each of those permanents.
{2}{U}{U}, Discard Vedu: Create a token that's a copy of Vedu, the Deepdrinker, except it's 4/4 and isn't legendary. Activate only as a sorcery.

Haste
Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
If a player casting a noncreature spell would cause an ability of a permanent you control to trigger, that ability triggers an additional time.

As long as you control exactly one creature, no more than one creature can attack or block each combat.

Choose one—
• Destroy target permanent with mana value 2.
• Return target permanent card from a graveyard to its owner's hand.
Exile Veil's Recovery.

{B}: Veilborn Hunter gets +1/+1 until end of turn.
Sacrifice another creature: Veilborn Hunter gains indestructible until end of turn. Tap it.

Flash
When Veilborn Meddler enters, counter target spell if its mana value is less than or equal to Veilborn Meddler's power.
Whenever you cast a spell during an opponent's turn, put a +1/+1 counter on Veilborn Meddler.

Menace
Whenever another creature dies, put a +1/+1 counter on Veilborn Stalker.

{1}{B}, Sacrifice a creature or enchantment: Draw a card.
{4}{B}{B}, {T}: Return target creature or enchantment card from your graveyard to the battlefield with a veil counter on it. That permanent gains “If this permanent would leave the battlefield, exile it instead.”

Whenever Veiled Charmer attacks, target creature blocks it this turn if able.

When Veiled Transmuter enters, you may cast an instant or sorcery card with mana value 2 or less from your hand without paying its mana cost.
Magecraft — Whenever you cast or copy an instant or sorcery spell, create a 2/2 blue Reflection creature token.

Flying
Concord — At the beginning of your upkeep, if there are four or more card types among permanents you control, exile the top card of your library. You may cast that card this turn without paying its mana cost.

Until end of turn, you may cast creature spells as though they had flash.
Creatures you control can't be the targets of spells or abilities your opponents control this turn.

Menace, lifelink
Once during each of your turns, if you would gain life, you may create a tapped Treasure token instead.

When Veins of the Intisuyu enters, draw a card, then choose a card name.
Whenever you cast a spell with the chosen name, search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Lifelink
Prevent all combat damage that would be dealt to embattled creatures you control. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)

Whenever you cast a noncreature spell, torment each opponent. (They lose 3 life unless they discard a card or sacrifice a nonland permanent.)
{3}{U/B}{U/B}: Draw a card for each opponent with ten or more cards in their graveyard. You lose that much life.

[+2]: Destroy up to one target monocolored permanent.
[–3]: Create an 8/8 Elemental creature token with flying, first strike, vigilance, trample, and lifelink that's all colors.
[–5]: Draw three cards. You pay {0} rather than pay the mana cost for the next spell you cast this turn.
