What units to use as games goes on

[rollems]

Well thanks to all the advise above i have been able to understand game little better. so now i am trying No loss. (did not restart the game but trying from where i was). i assumed it was possible as i am playing Paladin character on normal.
Right now i am stuck at Verona... kitting for map is just not happening for me even with that trick of save pause etc...
i will try to summarize my game. if you guys can point out what to do next to avoid losses or use units better. (i have killed all units/heroes in Debir/Scarlet/Bolo including Hero gaurding treasure in cave.) things left on Rusty are ZagZag and one Archmage gaurding Map. Verona have stolen Debir's wife. killed some enemy saying strong/very strong. Mostly with No losses after 1 Black dragon from Bolo (call of coll..).

My Stats.
Amelie Lvl 16, Leadership 4975
Attack 11 , Def 26 , Intelect 7
Gold: 150K
Rage 26 , Mana 30
Scrolls: Lvl2 Trap/Stone/OilMist/Pain Mirror/Slow
Lvl1 Healing/Helpnessness/Phantom/Avenging Angel/Bless

Units.
1 Black Dragon
1 Green Dragon
22 Paladins
24 Archmages
50 Inquisitors
3 Cyclopes
i swap Cyclopes with Green Dragon. based on situation.

Other Units in castle are Gaurd Droids/Repair Droids/royal snakes/polar bear.
and lots spider/snake/thorns eggs


so basically what way to proceed? what tech to focus and how to use the units i have even better.? what area i am lacking? how to kill those lethal units gaurding maps.

Edit: i am also running short on Ruins (Mind specially). though i have neatness Lvl1
