When this creature enters, create a tapped Powerstone token. (It's an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.") {1}{B}{R}, Sacrifice another creature or artifact: Until end of turn, other creatures you control get +1/+0 and gain menace and haste.

{T}, Sacrifice a Forest: Add three mana in any combination of {R} and/or {G}.

Flash When this creature dies, if it's not a Spirit, return it to the battlefield under its owner's control with four charge counters on it. It's a Spirit Detective. (It's no longer a Human.) {1}{W}, {T}, Remove a charge counter from this creature: Destroy target creature that dealt damage to you this turn.

You may exert this creature as it attacks. (It won't untap during your next untap step.) Whenever you exert a creature, reveal cards from the top of your library until you reveal an Equipment card. Put that card onto the battlefield attached to that creature, then put the rest on the bottom of your library in a random order.

Menace At the beginning of your upkeep, reveal the top card of your library. Any opponent may have you put that card into your graveyard. If a player does, this creature deals damage to that player equal to that card's mana value. Otherwise, put that card into your hand.

Flying Whenever a player casts a nonblack spell, that player loses 1 life.

Whenever a player attacks with one or more creatures, destroy all untapped non-Wall creatures that player controls that didn't attack, except for creatures the player hasn't controlled continuously since the beginning of the turn.
