I've been struggling with pirate warrior, my toughest matchup for sure in the final push for legend, I've tried improving that matchup some more by adding Muster for Battle in place of Ragnaros the Firelord since I'm already heavily favored vs control with the Anyfin Can Happen for 24 burst to close out any game. Doesn't help to weaken Drakonid Operative either.  :)

Would Argent Squire be a good replacement for Argent Horserider to help try and get the board? The few other cards I would maybe consider removing are Coghammer and one copy of Defender of Argus even though he is insane with all the divine shields. Cards I will not consider taking out are Argent Protector, Echoing Ooze and Blessing of Kings, they are just too valuable in my deck even if they are rather situational.

I don't know what you could trade for this, but if you are rocking divine shields for your non-murlocs then Corrupted Seer could weaken your opponent's minions (except in a mirror or Everyfin is Awesome Shaman) there is also the good old fashioned Equality

EDIT: as for replacing certain cards, just do what you think will help.
