...and can you please tell me which cards should i add and remove to make my shadow site raider archer?! tnx
I've played with a similar shadow before and
High Vantage is a must if you're planning to have guys survive to put tokens on
Harsh Tongues. Also, if you wanted to go more archer themed
Raider Bow helps a lot and gives extra twilight so you could possibly max out a
Harsh Tongues in one regroup phase if needed. I also splash a copy of
Haradwaith. If I grab it early, it allows my guys to put a nice hurt on a freshly healed fellowship right after the site 3 sanctuary and even if you get it later, you can discard an unwanted extra copy of
Harsh Tongues, etc. as a one time cycling help and twilight boost. Oh yeah, and
Mumakil 
are fun and brutal with this deck type.
