Goblin Secret Agent

Whenever a player's skin or fingernail touches this creature, that player loses 2 life.

Choose an artist. Exile the top six cards of your library, then reveal cards from the top of your library until you reveal a card with art by the chosen artist. Put that card in your hand and exile all other cards revealed this way.

As this enchantment enters, choose an artist. Creatures with art by the chosen artist get +2/+2.

Add R for each nonland permanent with art by the artist of your choice.

Choose a nonland card name, then reveal the top card of your library. If that card has the chosen name, you draw three cards.

You and target creature's controller have a staring contest. If you win, destroy that creature.

As this creature enters, you secretly put six or fewer +1/+1 counters on it, then an opponent guesses the number of counters. If that player guesses right, sacrifice this creature after it enters.

This creature enters turned on. Whenever a player casts a spell, toggle this creature's ON/OFF switch. As long as this creature is turned off, it can't attack or block, and prevent all damage it would deal.
