The title is the list!
-2x Stormsmith Stormcaller (2)
So first and foremost I know there are probably some glaring oversights (like stealthed units, etc) that this list might have issues with. This wouldn't be a tournament list that's for sure lol.
Anyways, Haley can hide between the two Stormwalls if they're base-to-base (since they can't be slammed/placed, etc, they'd actually block LOS to her), while she upkeeps Arcane Shield on one of them and casts Temporal Barrier every turn (and can still save two focus to prevent the Stormwalls from having spells cast on them). If infantry get too close, she can chain-lightning one of the Stormwalls to auto-hit it (and do nothing) and leap D3 times to nearby infantry while the Stormwalls do covering fire or just 2D3 shots each (and do Leaping Sweeps if necessary). If a Heavy Jack gets too close, the Stormwalls can double-hand throw it, slam it, or just punch it in the face with their POW 20's (that probably are hitting with a +2 from Temporal Barrier). Also, by dropping two pods and four Covering Fire templates combined with Temporal Barrier, they can control quite a bit of the board around them. Haley can also give three focus to each Stormwall while still upkeeping Arcane Shield the turn she wants them both to pick stuff up. Also, double pods + Stormcallers = awesome.
At 35 pts in an average, every-day game, what are you doing against 4 boostable POW 15 Big Gun shots at 14" plus 4 POW 12 stays-in-play AOE 3's at 10" plus two POW 10 pods at 10" that can disrupt, followed by some potential POW 10 Triangulations? On Feat Turn that's 6 boostable POW 15 Big Gun shots at 14". You can't cast spells on them, you can't shoot Haley or cast stuff on her, you can't move my Colossals, you can't knock them down, you can't charge them, and you'll probably never successfully arm-lock them. How's that for a fun and gimmicky list?
