The plan is simple, cycle through your deck and replay you permanents effects over and over again.

your three permanent options are Brouilleur Blindé for removal, L'Ouroboros, Bastion Lyra for card advantage, and Ruche des Scarabots for stats. use everything you have to repeat these effects to win expeditions and keep you opponents locked down with aggressive sabotage.

cards that have discard effects are essential, as they can get your hero ability online early and they are a free way to get value out of your permanents. here are all the cards with this effect:

• Gibil
• Jian, Superviseur d'Assemblage
• Inari
• Mécanicienne de la Fonderie
• Chroniqueuse Lyra

Every card that is in you hand, is a card that is not in you reserve, so cards like Élémentaire de Kélon, as well as you hero ability are essential. Everything else in the deck should be focusing on the gameplan, either repeating permanent effects or cycling through the deck faster.

For Uniques, anything that has "activate the on play abilities of target permanent you control" is what you want to look for, especially if it is a discard effect. when making room for uniques the best cards to cut are probably one Brouilleur Blindé, one Entraînement Mécanique, and one Boum !, becasue you are able to move through the deck so quickly these cards are the easiest to run fewer of.
