Goombario, Tattling Expert

{1}: Reveal the top card of target player's library. If
it's a creature, investigate. If it's an artifact, create a treasure token. If it's an instant, sorcery, or enchantment, target creature you control gets
ward {2} until your next upkeep. If it's a land, target creature you control explores. You can only target
each player once per turn.
