Auntie's Snitch can't block.

Prowl (You may cast this for its prowl cost if you dealt combat damage to a player this turn with a Goblin or Rogue.)

Whenever a Goblin or Rogue you control deals combat damage to a player, if Auntie's Snitch is in your graveyard, you may return Auntie's Snitch to your hand.

Whenever you surveil for the first time each turn, Whispering Snitch deals 1 damage to each opponent and you gain 1 life.
