Normally Cantrips heighten automatically. The primary exception being if it is cast from an item that specifies the spell Rank (or spell level for legacy items) that the Cantrip is cast at.
Cantrip Deck does specify the level as level 1. So yes, Rank 1 - not Heightened.
As an extension of the rules, I don't see anything wrong with adding a 'Full Pack' deck that has a different set of Cantrips in it. Might even be nice to have some that are on a theme. It might be a bit much to have a 'Full Pack' deck that has all available Cantrips in it for the same price as the one that only gives 24 of them.
Also, as an extension of the rules, I don't see anything wrong with adding a higher item level version of the Cantrip Deck that casts the Cantrips at a higher spell Rank and spell bonus/DC appropriate to the item level. The price of those decks should be adjusted to also be appropriate to the higher item level.
I would also allow Crafting a Cantrip Deck 5 pack of a non-Common Cantrip that the crafting character knows or has access to.
