If you're going to combine Performages with Darklaw.dek, then you should probably stick with the Clownblade Engine.
At the very minimum, the engine is:
1 "Heroic Challenger - Thousand Blades"
1 "Performage Trick Clown"
____________________________________________
But you may fair better with the following:
3 "Performage Juggler"
2 "Heroic Challenger - Assault Halberd"
1 "Heroic Challenger - Thousand Blades"
1 "Performage Trick Clown"
1 "Performage Hattricker"
1 "Performage Mirror Conductor"

--Juggler is just good at blocking damage, aside form the searching
--Halberd can search, but it also helps with cranking out R4NKs better
--Blades combos with Trick Clown, to the point where Trick Clown "summons" Blades
--Hattricker is the same as Halberd, in a sense
--Mirror Conductor, as either a scale or a monster, can help you simply walk over a large number of monsters by changing their ATK/DEF into something less than 1000. It's the OCG's main out to Raffle and Iggy.
