Trample
When Rosenhulk enters, choose one —
• Create two 0/1 green Plant creature tokens with “{T}: Add {G}.”
• Destroy target artifact or enchantment.
• Rosenhulk fights target creature an opponent controls.

This land enters tapped. As it enters, choose a color.

Haste
Whenever this creature attacks, destroy up to one other target permanent. If you do, its controller reveals cards from the top of their library until two cards that each share a card type with that card are revealed and exiles those cards. That player puts the exiled cards onto the battlefield, then shuffles.

Changeling (This card is every creature type.)
This creature enters with four -1/-1 counters on it.
Whenever another creature you control enters, if that creature has greater power or toughness than this creature, remove a -1/-1 counter from this creature.

Target creature gets +3/+3 until end of turn. If this spell was foretold, it gets +5/+5 until end of turn instead.
Foretell {1}{G} (During your turn, you may pay {2} and exile this card from your hand face down. Cast it on a later turn for its foretell cost.)

Exile target artifact, creature, or enchantment. If that permanent's mana value was 3 or greater, its controller may search their library for a basic land card, put it onto the battlefield tapped, then shuffle. (A transformed permanent retains the mana value of its front face.)

Menace
At the beginning of your end step, if you gained or lost life this turn, look at the top card of your library. You may reveal it and put it into your hand. If you do, you lose life equal to its mana value. If you don't, you may put it into your graveyard.

Target creature you control gains lifelink until end of turn. When that creature dies this turn, return it to the battlefield under your control with a +1/+1 counter on it. It becomes a Vampire in addition to its other types.

When this creature enters, each player discards a card. Then return an instant or sorcery card from your graveyard to your hand.

When this creature enters, you may discard your hand. If you do, draw two cards.
Other Pirates and Rogues you control get +1/+1.
Once each turn, when you discard a card, you may create a 1/1 red Pirate creature token.

Defender
This creature can attack as though it didn't have defender as long as a Pirate or Rogue entered under your control or you cast a noncreature spell this turn.

Discard any number of cards, then draw that many cards plus one. When you do, return target nonland permanent card with mana value less than or equal to than the number of cards discarded this way from your graveyard to the battlefield tapped.

Flying
When this creature enters, put a -1/-1 counter on a creature you control.

Put target nonland permanent into its owner's library second from the top. Surveil 1. (Look at the top card of your library. You may put it into your graveyard.)

When this creature enters, you may put a -1/-1 counter on a creature you control. If you do, look at the top five cards of your library. You may reveal a land card from among them and put it into your hand. Put the rest into your graveyard.

When this enchantment enters, exile target creature until this enchantment leaves the battlefield.
