Hi everyone! Been stuck on this map for a really really long time and I can’t seem to bypass it without losing team members.

My lineup:

Dimitri - Great Lord

Byleth - Falcon Knight

Ingrid - Falcon Knight

Petra - Falcon Knight

Yuri - Trickster

Lysithea - Gremory

Felix - Assassin

Shamir - Bow Knight

Catherine - Swordmaster

Seteth - Wyvern Lord

Flayn - Dark Flier

Mercedes - Gremory

I’m not even sure what the last strat that I was trying was, but I’ve just had no success on this map. Any suggestions?

The last setup I’ve tried is

Lysithea, Felix, Seteth, Flayn on the left

Ingrid, Byleth, Petra, Mercedes, Dimitri in the middle

Catherine, Shamir, Yuri on the right

Any tips would be appreciated

EDIT: Cleared with no issue. I had enough fliers to bully Cornelia right after taking out her archers. Didn't need Warp either.
