Any idea on how to beat a turtler?

The important thing we need to see, here, is whether you or your opponent is sitting on a material/Wit advantage. If your opponent vastly outnumbers you, then you've already lost. If, on the other hand, you have a small collection of Mobis, you can build a Bombshell Strike Force! It's possible to gradually break down a Bombshell wall, but if he's been banking Wits, then you're getting ready for one uphill battle.
