Equipped creature gets +5/+5.
Whenever equipped creature becomes blocked, destroy all other creatures.

Whenever you draw a card, put a dream counter on Stargazing.
Remove seven dream counters from Stargazing and exile it: Shuffle your hand and graveyard into your library, then draw seven cards.

Reveal the top five cards of your library. An opponent separates those cards into two piles. Put one pile into your hand. You may cast a nonland card with mana value 3 or less from the other pile without paying its mana cost, then put that pile into your graveyard.

Creatures you control have vigilance.
At the beginning of combat on your turn, you may tap target creature.

Discard a creature card or sacrifice a creature or exile a creature card from your graveyard: Put a +1/+1 counter on Starving Stalker. Activate only once each turn.

You may exile cards you own as you reveal them. (You see the card before you exile it.)
During each of your turns, you may cast a card exiled with Starwing Nebula.

Until end of turn, if a source you don't control would deal damage to you or cause you to lose life, mill that many cards instead.

Create a 3/3 black Demon Horror creature token.
