first off 3 leo is pretty importent in all builds hes your main search engine
secondly heraldry change shouldnt be ran in 3 even running it at 2 or 1 isnt really necessary cause cards like pinpoint guard are way better
third i dont understand why there is 2 shadow mirrors are there even any competitive dark archtypes this format. that card should be sided
fourth summoner monk is a great help in this deck since it runs many spells
also teh monster trap isnt necessary whatsoever (cant remember or see the name)
also instead of rank up barians force you could run limited barians force or numeron code both are better
your really missing out if u dont run s.h ark knight
