Any replacement for Myra's Unstable Element? Would a Sprint be good enough?

 Seems good, not sure about having 4 weapons. Here's my version of aggro pirates

The big problem you have here is thinking that Bazaar Burglary is an aggro card, that is 100% a control card to keep aggro at bay, way too slow for aggro. And having 4 weapons is fine when you don't have raiding party. Before cards like Forge of Souls or Raiding Party existed, you would find that having 4+ weapons in deck was fine.

I definitely think you're right to try and weave in a Preparation though, seems needed in a true aggro rogue.

Bazaar burglary is very good as tempo card. It turns you into odd rogue and all you need to activate it is to expand a little bit into the already good burgle shell

This is a stretch, but do you ever put Zephrys the Great into the deck in the hopes of finding extra burn after Myra's?

I don't think so, you would need to draw him just before myra's or with myra's (which also means you would have to draw myra's), if not it's either just going to be 2 mana 3/2 or get discarded.

its seems to be a great deck
