A new trick for a (currently) 1 trick pony, help w/ character for nick012000's game Options

[Divine Virus]

Alright, I am joining in nick012000's Leuge of Justice superhero SR4 game, cause it looks like fun and I have reached a crossroad with my character, and I don't know what to do, so I turn to the more expeinced for help. This character is currently, a one-trick-pony (counterspelling, which he has in spades), however with 288 BP left (its a 470 BP game, with no restriction on availibilty, or the ammount of BP spent on equiptment) I think it would be wise to pick up a second trick.

Disclaimer: I do not consider myself a munchkin. I may (frquently) be guily of min/maxing, however my characters always have a damn good story behind them, and a dominent roleplaying aspect. I have never made a character for the sake of c00l p0w3rz. (well, ok, I did once, but just because that paticular GM needed to be knocked down a peg or two. Long story.) I say this because, well, I am DAMN good at counterspelling, with a base 12 dice plus will/body.

Basically, here is what I have of my character so far.

Mystic Adept (10 BP)
Aptitude (counterspelling) (10 BP)
Counterspelling 7 (32BP)
Counterspelling foci(rating 5): Combat (10 BP with bonding)
Counterspelling foci(rating 5): Detection (10 BP with bonding)
Counterspelling foci(rating 5): Healing (10 BP with bonding)
Counterspelling foci(rating 5): Illusion (10 BP with bonding)
Counterspelling foci(rating 5): Manipulation (10 BP with bonding)
Logic 5 (40BP)
Magic 5 (40 BP)
Total 182 BP

giving me 288 remaining, 160 of which can be spent on my remaining attributes. This Character has a strong theme of the mysterious, myth and identity. For this, I have several options.
1) illusion/manipulation mage
2) stealth M. Adept
3) unarmed M. adept
4) unarmed/stealth M.Adept
5) full support character (i.e. healing magic and a crapload of mystic armour)

The thing to consider are that
A) the counterspelling foci take up all the foci make up all the foci I can have active at any given time. Thus I cannot have any sustaining foci, and will have to sustain all the spells myself, a large hinderence considering its illusion/ manipulation I am talking about and B) that my main purpose for this character is to protect the other group members from incoming spells.

Thanks for you suggestions,
DV
