After several months of testing, I am glad to say that my aforementioned Shadowrun Initiative Cards have been a phenomenal success with my weekly game.
I've since modified them, added new cards with new effects, and fun doo-dads for the players. Current;y, I'm working on adding Contact Cards, which you "tap" when they are in use, and adding "Task Cards" to keep track of which contacts are doing what favors in the background.
So far, the cards have been a phenomenal success. I run a group of 7 players, and these cards greatly help keep combat flowing, split-party locations managed, and background tasks compartmentalized. I figured I would share these with you, in case any of you folks like the cards and gain some kind of inspirations from them.

FYI: they work well when placed in a clear card sleeve, with a card from the SR:tCG used as a backer.
EDIT: I should note that pages 11-14 are Glitch cards, drawn from a deck when a player glitches. So far, the group likes the se a lot more than normal glitch rules.
