This card is confusing. In a 2-player game if you're playing as Averni and Belgic. As the Arverni can you take the action and place Belgic ally tokens down on subdued spaces since the card says "any available gallic allied tribes desired". It doesn't specifically say your faction. Full card text is always appreciated since it saves those helping you having to look it up
A lot of the cards are really odd to read grammatically so I'm just trying to understand how this wording works.
Hillforts: Place any Available Gallic Allied Tribes desired at any Subdued Cities not under Roman Control. Then replace any Gallic As you already wrote, the card says any faction and that's exactly what it means.
Allies at any Cities desired with Available Citadels of the same Faction.
Yes, this is more powerful in a two player game than in a four player game where it would help another player.
Most of the unusual grammar is because the text is written to mean exactly what it says.
