For the runes, I personally don't find it distasteful to check the net a little bit for advice. There are a ton of runes and most of them are useful, only a few terrible, and none that are so game-breaking that you have to use them. Plus, it would take forever to playtest all the combinations yourself.
I'd say the Anvil of Doom playability starts at 2000 points and increases in likelihood as the points go up. I heard that nearly all the Ardboyz dwarf lists brought along Thorek.
The old Anvil is honestly the only really viable way to play dwarfs that move. Otherwise it's just the turtle game while you attempt to obliterate the enemy with 4 bolt throwers, a cannon, an organ gun and 3 units of thunderers.
With the anvil you have use it's ability to propel units during the shooting phase to actually get charges off, and to bring a unit of miners onto the board and then charge them in during the shooting phase. Seriously, it increases the effectiveness of miners by about 200%.
And if you do tote along the Anvil, there's no reason not to bring Thorek Ironbrow. Ancient Power on a 4+, or Ancient Power on a 3+ with a reroll? Hardly a question.
