Here it is: number each of the spots in clockwise or counterclockwise manner starting from where you want and you'll have yourself a solid pattern to follow should you wish to have a specif arrow arrangement for EACH card - OR, if you're only worried about the 7 cards with limited availability, keep note of their order in the sequence.

4 arrows:

7 first: {a,b,c,d} {a,b,c,e} {a,b,c,f} {a,b,c,g} {a,b,c,h} {a,b,d,e} {a,b,d,f}

7 last:{c,e,g,h} {c,f,g,h} {d,e,f,g} {d,e,f,h} {d,e,g,h} {d,f,g,h} {e,f,g,h}

5 arrows:
