here are my recommendations for your blue dragon deck, some are (imho) improvements, other are choices to consider.

• swap the humvee cv for a inf cv in a fast vehicle. It is easier to hide and you already have a tank cv.
• get rid of the shosung su and get a card of soshung su 85 in kav 40/50 (grenade launcher transport) or get buntai 90 in wapc (wheeled grenade launcher transport and inf with carl gustaf)
• swap the kutei 90 for a card of buntai 90 in hacky kyu shiki (awesome ifv). For fighting inf, you already have 14 heabyungs 90 and 5 teukjeonsa's
• consider replacing the kooryung with a k9 thunder, it one of the best tube artillery in game, although the rockets are nice for stunning when attacking a position.
• Nice aa setup
• Nice 2 tank choices, but where is your k1? It is the best medium tank in bluefor at 85 points and works great as meat shield for your yon shiki g's (also a great tank)
• swap the oh-6 and get card card rangers, at 30 (in a truck) pts, it is nice cheaper recon unit that is also a 10 men shock inf with smg (great in forest) and sniper rifle. They could also be your fifth card.
• vehicle tab is nice (there is a nice 20 pts chu-mat jeep, but tow 2 is also fine)
• good helicopter choices, a rocked spammer and a gunship
• drop the dragonfly. The dragonfly is a piece of shit, slow, no ecm, not enough bombs, 2 missiles wont do enough
• put in a f1, it is a fast bomber that can also kill tanks if you target them (guided bombs) (they hit top armor and 1 shot anything 2 armor and almost kill 3 top armor). They can also position fire bombs.
• f5a is nice if you need napalm

This will give you some activation points issues, so drop 1 vehicle tab unit and get the k1. The points you get with dropping the dragonfly, can be used for a f1 or a 5th recon as mentioned earlier. Concluding, a nice deck, that only lacks the k1 and the grenade launcher transport goodness that blue dragon has.
