Hmm let's see for skills.
As a Mage you want Spellcasting, Summoning and Binding. Summoning test aren't too hard so it can be left at 5 (with the points you get from Magic A), Spellcasting and Binding at 6. With an Intuition tradition Assensing is a good pick but it's a non opposed test so you don't need too much, picking 2 points with Karma should do the trick. Counterspelling is always a good idea, let's put 3 points in it.
As a runner the skills you use a lot are : Gun option, Sneaking, Perception and Etiquette. With your low AGI sneaking won't do much, you will need to rely on Invisibility for that. For ranged option Automatics is probably the best since burst will allow you to remove defense dice and actually land a hit. So we get 5 in Automatics, 2 in Perception (with Karma), 4 in Etiquette.
So we end up with : Automatics 5; Binding 6; Summoning 5; Counterspelling 3; Etiquette 4; Spellcasting 6; Summoning 5. And you have 3 Skills point left for specializations. Now with Karma we add 2 Assensing, 1 Diguise, 2 Perception for 14 karma. Since you have high WIL and INT the Outdoors skill group could fit well on your character, and well Hippo are pretty good survivors right? Let's spend 5 karma to get the skill group at 1 for a total of 19 karma spend in group.
See I got you all the essentials and I fit a gun skills in there for those time where it's better not to reveal you are a mage or simply when shooting will work better than a Stun/Lightning bolt.
