So far:
Monarchs (great handling and stock)
Steampunk (design looks great in circular and spinning flourishes)
Medallions (the design is great)
Artisans (they handle very well)
deckONE (the design is really unique and the box looks amazing)
1. Because the box looks awesome and the card handles really well.
2. Because it has an amazing back-design. Also the box looks really nice.
3. Same as 2.
4. Because they are not too expensive but still handle amazingly. And they look pretty cool with certain flourishes.
5. Because they have an interesting beck-design and they handle like all bicycles; really well.
