This card is not very good with its base stats, but if you are playing against a battling deck then dengar is well worth it.
it is at least power 3 because you have to be battling something, and most likely if your opponent is trying to win the battle then the numbers will just go up.
Strategies and game play:
use dengar to increase your power and win battles.
Combos with other cards:
use with other bounty hunters to get battle destinies or with "all wrapped up" to capture characters. Also there is "after them" which is a great combo because it almost forces your opponent to battle you and dengar is most useful when he is battling.
Ways to counteract it:
Master luke and jar jar or any weapon should hit him
about power 10 on average
