What if it's simple as:
Creature Base Taming% * (1 + Taming Skill% + Card 3% * Card's +) So if Angel is 5%
Then 10 + 4 is: 5% * (1 + 50% + 3% * 4) = 8.1%
And if Hawkman is 15%
Then 10 + 4 is: 15% * (1 + 50% + 3% * 4) = 24.3%
And if Blue Pixie is 45%
Then 10 + 4 is: 45% * (1 + 50% + 3% * 4) = 72.9%
I used those measurements based on what people are inclined to say.
That and each one is a factor of 3x less chance. (5 / 15 / 45).
Simiplest solution is best.
Rare:
10 = 7.5%
+1 = 7.65%
+2 = 7.8%
+3 = 7.95%
+4 = 8.1%
+5 = 8.25%
+6 = 8.4%
Uncommon:
10 = 22.5%
+1 = 22.95%
+2 = 23.4%
+3 = 23.85%
+4 = 24.3%
+5 = 24.75%
+6 = 25.2%
Common:
10 = 67.5%
+1 = 68.85%
+2 = 70.2%
+3 = 71.55%
+4 = 72.9%
+5 = 74.25%
+6 = 75.6%
If that fits. Then that is great. If not figure what you like.
