Just to Clarify...
Blucher is game where you can use Unit cards instead of miniatures (and if you do, you can use maps / flat boards for scenery and it be kind of cool) and uses tape measures and Dice for 'resolution mechanics'. You can get card sets for 'armies' from a print on demand service that comes professionally sorted out.
Might and Reason is a 'traditional' wargame, no cards, designed for dice and models
Maurice uses miniatures and tape measures and scenery, but uses cards to control and influence the actions and handle things like notable sub commanders and national characteristics.
So, Blucher is the easiest game to buy and play - no models needed
Maurice is indeed made interesting by its action cards (not to say Blucher ISN'T interesting!) but assumes you have the 'kit' for traditional wargaming
Might & Reason covers similar ground to Maurice, but without the cards
Sorry if you'd already wrapped your head around that but I wasn't sure - your comment about Unit Cards for Maurice (which doesn't have them) made me think you didn't.
You can find links to sample Blucher cards with a bit of hunting in the Blucher forums, you should also be able to find links to where one can get the cards which usually shows previews. Note that some samples may be from the Printed Expansions (which you will now struggle to find in shops) so might not exactly match the Print on Demand stuff, although quality is similar.
From what you're asking I'd also recommend Blucher, it was, it's sort of a gateway to miniatures in some way as it plays like a miniatures game without the models
