Why have you decided to waste the combat potential of the squad? At 1000pts a combat heavy cheap character, like the wolf guard will really mess up your enemy. There will not be too many
pf or power axes to get through the 2+. If you pop the banner then the
TDA will be nearly untouchable. I'd look to re-tool these guys. The rune priest is the combat weak model, not the
WG.
For the same cost you could have 3 wolf claw/
ss models. Yes they will such against 2+ saves but they will clean up when it comes to 3+ saves.
If you are really worried about 2+ saves you could just go with a
ss and a power axe. Cleave the head off and it comes with the
TDA.
