BTW, Chase, you should be aware of something. The army setup with fairies and such is good up until the battle with Bagum (the big orc that gets you to the turtle via his flying contraption). Bagum has a lot of hard-hitting lvl 4 Orc veterans, Shamans and other units which makes your army a bit improper for that fight. Although it's still manageable, it will take quite a lot of resurrecting afterwards.
The turtle head battle will be even harder because dragons eat fairies for breakfast... However, with the boost in damage you have (whip + dagger) you may be able to cut it, but the ressing will be long and arduous... But I guess that's why it's a challenge

One ancient ent and you'll be set to start with the neat trick with multiple thorns and poison cloud lvl 1 you pointed out
