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

your four permanent options are Brouilleur Blindé for removal, L'Ouroboros, Bastion Lyra for card advantage, and Ruche des Scarabots or Cabas à Scara 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.

Updates: New set new cards! but I don't think there is much that will change for this deck. the strategy is too specific so the card selection has to stay focused, but there are some good options. Cabas à Scara is a great way to get more stats early game before you can get a hive out, and I think making a way to get Icare in could be helpful, as this deck is weak to exhausting. Unité Lab Tech could also be a good option, and potentially a replacement for the ouroboros, but I think the card selection is too valuable to give up.
