Spyglass Siren {U}
Creature — Siren Pirate
Flying
When Spyglass Siren enters the battlefield, create a Map token. (It’s an artifact with “{1}, {T}, Sacrifice this artifact: Target creature you control explores. Activate only as a sorcery.”)

Token Artifact — Map
{1}, {T}, Sacrifice this artifact: Target creature you control explores. (Reveal the top card of your library. Put that card into your hand if it’s a land. Otherwise, put a +1/+1 counter on this creature, then put the card back or put it into your graveyard.)
Map tokens are cute, very nice way to get extra mileage out of keywords. When artifact tokens were first introduced, I figured we’d be done with them when they went through all the basic resources (mana, cards, life). But it seems they have far more design space than I first thought
