The troop deployment before the attack is as follows:

(3 water elementals) (1 butterfly)
(45 maxmen) (5 cavalry) (1 butterfly)
(64 pikemen) (1 butterfly)
....

Round 1:

Cavalry move: attack the lower group of griffons on the left, so that after the attack, the cavalry stands right next to the left side of the battlefield.
...

Even considering that the attack is planned on grass terrain, the cavalry (ungrained, speed 7, on grass 8) cannot attack from that distance, as it is 9. If they are upgraded (and this can be done for free in about 90% of cases in the outer stable), it is better to swap them with the butterfly from the 7-stack, then the range before the attack and occupying the desired cell will be 10 cells.
