i need to know if it is to risky to combine them for a regional tournament :ermm:

Can you define 'ss' and 'ms'? I assume you're not talking about secret police or Bill Gates...

i wanted to know if a silent swordsman and mystic swordsman deck combined to risky to run in regionals?

It might work out, considering that they're both warriors and that should tie them together. Don't use Silent LV7 though, it just might bog you down too much. If you want, you can post the deck in the UDE Deck Depot (if you haven't already) so you can get more accurate suggestions for your specific deck.
