By far my favorite character to use w/ the Sneak ruleset is the Vigilator; bc it has both melee + range attacks (as well as double-strike) it allows the Vigilator to strike 4 times in a row...add in a melee character with Inspire (+1 melee) in front of it & make sure it's got some "padding" around it so it can stay close to the middle for as long as possible, & you've got yourself a character that will drive your opponent nuts...there's been a few times where once it was the Vigilator's turn to strike in a match, it took out my opponent's entire team - takes out a character, 3 strikes still left to go...next character doesn't have much health so they're the next to go, and you've still got 1 melee attack & 1 range attack left to go before the other team strikes again (at which point they're usually left with a Chicken or Gelatinous Cube, lol).

If you're lucky enough to own a Vigilator, it's probably my favorite ruleset (assuming there's enough mana to allow for it to work, that is). You can obviously rent one too, although I presume it's a rather high daily rent these days...Plus, technically any melee character with double strike will do very well in that ruleset; it's just that the Vigilator has that fun extra bit of attack power that's 100% certain to annoy the hell out of your opponent...so there's that.
