I just got myself a U Deathbird and I dont know If I should use her for close combat or ranged combat.Sould I even be using her?And what feats should I use?

I love her, she can be very tough for her points.

8' range and high defense vs counter attack from a range attack. Keep her at range and take advantage of her 17 def plus 2 ES def = 19 def.

If you do get based well then she is able to handle it up close not bad either. 10 attack and BCF kicks butt. Slice and dice them up. She has pounded many enemies for me over time.

Now that all being said I do play 99.9% theme teams, she plays on my Xmen enemy team. Never thought about playing her in a tour b/c I don't like tour play much, too boring. I love theme play more.

Hope that helps

Trick Shot would be a must for her. This will also allow her to carry around a Hand Ninja as a human shield while modifying her AV. If she takes a solid hit she's done though, but she's always managed to dish out just enough for me when needed.

Range, Man!
She's a range figure!

Unless it's late in the game and you really need to base somebody with her, keep her 8 squares away on hindering terrain and blast people!
On hindering, her defense is 20 with her Energy Shield--and even if that's outwitted, it's still a respectable 18!

She's top-heavy, but she's still a great figure.

I wouldn't waste points on feat cards for her, but if I did I might use Force Field to give her 4 clicks of Toughness for 10 points.

Don't forget to bring some probability control to make sure others can't hit her and to help her do the most damage with her B/C/F.

Force field is a good Card for her, I wouldn't worry about Trick shot on her either. Her dial is to short and she loses RCE after only a few clicks.

I usually play Forcefield and Stunning blow on her. for an extra 20 points she get usefullness out of those 2 cards for most of her dial.
