When Whisper Collector dies, draw a card.

When Whisper Witch enters the battlefield, choose up to one target creature. That creature's controller mills four cards, then puts that creature on top of their library.

Flying, trample
When Whisper in the Rift enters the battlefield, target player mills half their library, rounded down.
When Whisper in the Rift dies, you may cast up to two instant, sorcery, and/or creature cards from among opponent's graveyards without paying their mana cost.

Return target card from your graveyard to your hand.
{1}{G}, Tap an untapped Shaman you control, Exile Whisper of the Wild from your graveyard: Return target card from your graveyard to your hand.

Put target instant or sorcery card from your graveyard on top of your library.
Inscribe {3}{U} ({3}{U}: Exile this card from your hand 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.)

Whenever Whisperer of Fortunes attacks, the next card you foretell this turn costs {0} to foretell.
Whenever you cast a foretold spell, put a +1/+1 counter on Whisperer of Fortunes. It gains flying until end of turn.

Creatures can't attack or block alone.

Whenever an opponent casts a spell, that player mills X cards, where X is that spell's mana value.

Menace (This creature can't be blocked except by two or more creatures.)

You may play an additional land this turn.
Return target permanent card from your graveyard to your hand. Exile Whispers of the Dark.

As an additional cost to cast this spell, sacrifice a creature.
Look at the top three cards of your library. Put two of them into your hand and the other into your graveyard.

Germinate three times. You lose 3 life. (To germinate, put a +1/+1 counter on a creature or create a 1/1 green Saproling creature token.)

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.”

When Whisperwoods Reclaimer enters the battlefield, if there are three or more land cards in your graveyard, return target land card from your graveyard to the battlefield tapped.

Prowess, haste
Mirage {R} (You may cast this spell as though it had flash for its mirage cost. If you do, sacrifice it at the beginning of the next cleanup step.)

Whenever Whitepeak Channeler deals combat damage to a creature, tap that creature. That creature doesn't untap during its controller's next untap step.

Vigilance

Alpha (You may have this creature enter the battlefield with a +1/+1 counter on it. If you do, it becomes alpha and can only attack alone.)

When Whiterun Ordainer enters the battlefield, you gain 4 life.

Flying (This creature can't be blocked except by creatures with flying or reach.)
Lifelink (Damage dealt by this creature also causes you to gain that much life.)

Escalate {B} (Pay this cost for each mode chosen beyond the first.)
Choose one or more —
• Wicked Blow deals 3 damage to target player or planeswalker.
• Wicked Blow deals 3 damage to target creature.
• You gain 3 life.

{2}, Sacrifice Wicked Fossil: Target player loses 2 life and you gain 2 life.
{2}{B}{B}: Return Wicked Fossil from your graveyard to the battlefield transformed. Activate only during your turn.

Each opponent sacrifices a creature. For each creature sacrificed this way, 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.”)

Menace
Whenever Wightclaw deals combat damage to a player, that player discards a card and you draw a card.
