When I think of manly cards, or boys' I think of CAS, minimalist, certainly no frills, preferably one or minimal layers.
So for my card I masked of a strip on the cardbase, inkblended Versamagix inks inside (Night Sky, Aegean blue and Aspen Mist).
I masked the moon off with some Inkadinkado masking paper before inking and kept it on whilst I was splattering Brushed Pewter Distress stain for my stars.
Then I stamped the Tim Holtz Santa Sleigh with Versafine Onyx black ink.
The sentiment is from Studio light and I also used Versafine for it, extended the stamp to the edges with a fineliner.
Seeing it's also one layer week as Less is More I will enter a second card there too.
