Hum
The hum is the half second where the viewer knows the tier before they know the card. The back's edge glows in the tier's colour, and the card moves: a small hop for a quiet tier, a side to side shake for a loud one, a longer shake for a legendary.
Open them left to right and watch only the back: each tier waits differently.
When it plays
Every card gets it, whatever its tier.
How it is built
The glow is a box shadow tweened from a faint white ring to a 70 pixel bloom in the tier's colour over half a second.
A quiet tier hops 8 pixels and settles in 0.4 seconds. A loud tier shakes 5 pixels each way in the same time. A legendary shakes for 0.7 seconds. That one number is the only thing that tells a legendary apart before it turns.
A press on the card during the hum skips straight to the turn. With reduced motion the glow stays and the movement goes.
