Sneak could possibly exchanged with Blend... which would be thematically more fitting, considering the fact that the team needs to stay under the radar.
Also, this is my first Sage build ever. The decision was to show that fate itself is on the side of the team with all of Hannibals Chance feats. It begins slow, by handing them more "loot" and slowly scaling up, until finally anyone in Hannibals path seem to have a bad day per Black Cat and Jinx.
Glint of Madness - to better use Threats in combat - and Basic Skill Mastery (Officer) plus Talented (Officer) shows his military background and moreover helps to save some skill points.
When it comes down to combat, the guy is no slouch, just no comparison for most of his teammates. But he is the one who brings the best out of them... and fabricating the most ridiculous plans, which would doom anyone else but the A-Team.
Assistance allows Hannibal to accelerate the efforts of his buddies, like a break in, building something on the spot... but not during downtime, it's more of a hands-on-approach.
Best of the Best allows him to hand out the best skill bonus for any task at hand... let's just say good old BA is kickin' some ass and Face needs to fix something right now... with Hannibal right there he can hand out BA's crafting skill ranks to Face.
Hand of Fate nets him a temporary Chance feat for an adventure.
Take Heart allows him to hand out some more fighting spirit to his team
Proven Worth gives him and his team some more Action Dice to use... which is always welcome and
Serdipity - his gamebreaker - allows him or the GM to invoke more or less a streak of luck on purpose.
Which allows the greatest customization to any Sage is the Cross-Training ability... you can shape a Sage in nearly any direction... handing him a bit of a Captain's abilitys, allowing him develop more easily contacts (Emissary) and many other things.
I hope it helps.
P.S. the rest of the Team would likely be Soldier/Keeper (BA), Courtier or Emissary (maybe both, Face) and possibly, just possibly Burglar/Scout
