Advice for impossible mage?

[Zechnophobe]

If you don't like to kit nav maps, get the emerald dragon on Rusty Anchor, and then Order 2 magic early on for healing it. That, by itself, can win most of the battles on the first 4 or 5 islands. Trolls, reds, bones, etc are just gravy and simplicity after that.

Well, this game is really easy once you know how to play, even impossible mode is a joke. Clearad all quests on all islands (apart for some special ones, like the main capital of verona and the last sppecial bosses) except sheterra (only partly done) and reha without ever losing a single unit. And I started this run after only 2 days of getting to know the game. They should really make the next game harder since this isnt a challenge at all. But however sheterra seems very hard for a mage, how do i beat for example a group of 40 green dragons and 35 black dragons? The greens isnt a problem because spells work on them, but how am i supposed to take out 35 black dragons?

the spells trap works on black dragons

and astral damage too(armageddon, death star)
