How to apply the effect "You may treat all Constructs as Mechana Constructs" in Ascension game?
Yes, once you have the effect of "You may treat all constructs as Mechana Constructs", this applies to acquisition (e.g. runes that can only be used to purchase Mechana constructs can be used to buy any construct under this effect) and to effects that count the number of Mechana constructs in play. (There may be other effects from later expansions.)
