Dragon Attack Question

What kind of base would 7 Lv1 Dragons, 25 lv3 archers, and 10 lv3 barbarians be able to beat? I have access to 1 lv1 rage spell and 2 Lv4 Lightning spells. What kind of base would this be able to beat, I never used dragons before so I don't know how strong they are.

3 air defense should to good if 1 is exposed. Kill the exposed one with barb distraction, archers over wall. Lightning the other air defense to death. Send it dragons.
