Sooo here is my Frontier list for the last game against a Perdita crew
Cornelius Basse + LLC upgrade (2ss)
Bernadette Basse
Reichart (10)
2 Austringers (14)
1 Pathfinder (6)
2 clockwork traps (4)
2 Frontiermen (10)
I was facing
Perdita Ortega + No prisoner upgrade (2ss)
Enslaved nephilim
Francisco Ortega (9)
Guild Steward (6)
Nino Ortega (7)
Santiago Ortega (8)
Abuela Ortega (5)
Papa Loco (7)
Strategy : Plant explosives
Schemes : I chose Outflank and Search the Ruins, my opponent went for Vendetta and Harness the Ley Lines.
A horrible positioning mistake by me, made me lose Cornelius at the start of Turn 2.
But, by then, my Austringers already killed Nino and Abuela (Nino was the chosen miniature to score Vendetta, by the way).
On the left side, my Pathfinder managed to put down one Explosive and a couple of Scheme Marker for Search the Ruins, while Perdita advanced toward the center to block Reichart (dead by turn 4). With him, there was a Frontierman, 1-shot by Santiago at the end of Turn 2. Pathfinder's traps managed however to block Santiago in the middle, making impossible for him to advance further.
On the right side, the Austringers dropped an Explosive marker behind a building and pinned down Francisco for a while, before getting killed eventually, releasing this way their Raptors that kept busy both Francisco and Perdita . By turn 4, all Raptors were dead, but my opponent didn't manage to advance an inch.
The Frontierman reached the enemy backline, dropping another Scheme Marker to score Search the Ruins, at the end of Turn 5.
In the end, I only managed to get 2 VP for Explosives, 2 VP for Search the Ruins, and 1 for Outflank, while my opponent scored 3 for Explosives and 1 for Harness the Ley Lines.
This Frontier list is not bad at all, lot of guerrilla-like tactics and I took advantage of my superior numbers to reach the backlines while Perdita and the Family were too busy dealing with Austringers and Reichart.
Bernadette was just "meh"...all she did was landing a "Bring it" on Papa Loco at Turn 3 to push him into Reichart's bladed arm, before getting killed by his demise ability. Probably that was stupid by me, even because she had 1 explosive on her and I kinda forgot the Papa Loco ablity to blow away people around him after getting killed
Sorry for the short and inaccurate battle report
