Yeah, those are a little tricky. One tactic is that you can hide behind a wall and use the 'wait until sighted' key, snagging them when they enter a range you can hit. Let 'em play by your rules, rather than going to them. Assassin start also immediately sets you up with a few cards of the highest range, great for these situations. Sometimes, though, you just need to use a jester, bring back your discarded, and take the hit.
