Whenever you sacrifice an artifact, put a +1/+1 counter on this creature and add {R}.

Haste When this creature enters, suspect it. (It has menace and can't block.) Whenever one or more other creatures you control enter, if this creature is suspected, you may suspect one of the other creatures. If you do, this creature is no longer suspected.

Prowess, haste Disguise {5}{R}. This cost is reduced by {1} for each instant and sorcery card in your graveyard. (You may cast this card face down for {3} as a 2/2 creature with ward {2}. Turn it face up any time for its disguise cost.) When this creature is turned face up, discard your hand, then draw three cards.

Haste {T}, Sacrifice an artifact: Put a +1/+1 counter on each Goblin you control. Whenever an artifact is put into a graveyard from the battlefield, you may pay {R}. If you do, create a 1/1 red Goblin creature token. It gains haste until end of turn.

Flying When this creature dies, you may exile it and collect evidence 4. If you do, return this card to the battlefield tapped. (To collect evidence 4, exile cards with total mana value 4 or greater from your graveyard.)

This spell costs {3} less to cast if you've sacrificed an artifact this turn. This spell can't be countered. (This includes by the ward ability.) Suspicious Detonation deals 4 damage to target creature.

As an additional cost to cast this spell, sacrifice an artifact or discard a card. Draw two cards.
