Funny and amusing situations...

The Gogs won't have enough ammunition, and besides, the wooden creatures will be divided into 6-7 stacks; you won't be able to control them all.

The Magogs will have enough ammunition. I don't believe it's possible to break through with simple Gogs.
The second problem is more serious, and there's also the morale issue. That's why it's interesting to try.
The question is about mercury for upgrading – either a simple upgrade for 5000 gold (112), or (in my opinion, better) a resource storage (112, leading to 113).
Market-storage-Magogs-second hero-full trade. This is if the Gogs are built.

If there are 35+ of them, even Maretti won't be able to break through to 113. And even if you do break through, you'll lose almost your entire army and end up running around the map with 1 Imp and armor – that's not a very good scenario.

Yes, the main thing is how many of them there are, and what the Castle can deploy at level 113.
If, for example, there are 26 Magogs, 32 Imps, and 4 Dogs + a ring, then it's not that bad.
It might even be very good, like Ballistas or a Spirit of Despair.
And you'll have to run around the map with Cerberuses (one more day for upgrading), Demons, and the remnants of the Magogs. Set up traps and citadels.
Although, if there are hidden spots or a lot of easy loot, maybe it will be possible to get Ifrits...
Ah, if only I had a save file...
