Of course not, no one was "waiting." Alright, I'll reveal the secret:
The army formation is as follows:
(starting from the left) 2 griffons, a green dragon, 1 griffon, 1 griffon, 1 griffon, 1 pikeman, then a green dragon.
1st turn: naturally, slow down, and with all creatures, fly directly to the maximum distance.
2nd turn: apply haste and position yourselves as follows: (starting from the top)
1 dragon, one dragon one cell down, (the rest also one cell down), BUT IMPORTANTLY, the group of two griffons must be the third from the top!
3rd turn: with two griffons, position yourselves on the 2nd and 3rd cells from the bottom in the right corner of the screen, with the other griffons, position yourselves on the row above, filling all 4 slots in the field so that the stones are to the left, then the "upper" dragon flies to the 4th and 5th cells respectively of the bottom row (also from the right side), and the second dragon from the top positions itself on the 2nd and 3rd cells of the third row from the bottom, so as to cover the griffons and simultaneously cast Blind on one of the archangels (any one, and this is not necessary at all).
4th turn: Blind the archangels that are on the 6th and 7th cells from the bottom in the right corner, and with the dragon above, press "D" and increase the defense by +6, thereby the archs will deal not 45 damage, but 37!
5th turn: Blind the archs that are above the dragons, and that's it!
The rest is done by Lightning, and there are still 68 MANA left! That's how the battle goes.

P.S. Theoretically, it is possible to win this battle, losing only the tent, but unfortunately, I couldn't do it.
