Orcs vs. Humans

There are some misunderstandings here:
If a Knight trains Paladins and rushes forward to attack, it means the Orc has problems because his rage definitely won't save him from that much damage, and Archangels can help without getting into the thick of it – they can resurrect!

The Knight will position his attack stacks in front, thinking he will be attacking, but who is going to give him that opportunity? After a couple of attacks from Cyclops before the enemy hero's turn, most of the army will already be destroyed.

The Orc will immediately take down (if lucky) or kill most of them (most often the free Cyclops!), and it will be easier, and the ability of the Harpy will not work so well (or rather, it won't work at all!) because the Paladins will have more space to gain momentum with that tactic!

The Paladins won't gain momentum – they will either be killed or thinned out and blocked. The Knight's tactic will play into our hands here – it will bring us closer to the enemy, not the enemy to us.

The problem is how the Orc will counter this, unless he has high initiative and attack! (if the Orc's attack significantly exceeds our defense, then the first spell should be mass stone skin!)

The problem is that when it's the Knight's turn to cast spells, he will look at the remnants of his army and there will be no need to apply mass stone skin or mass haste – there won't be anyone left to cast them on (and we shouldn't forget about Light Dampening). Only Subdue will stop the attack stack of the Orcs' relentless war machine. But even then, the Chieftains and Daughters will be able to finish off the remnants while the Cyclops will be significantly slowed down due to the Knight's low skill point (SP) stat (penalty on Subdue).

And even if the Orc doesn't use the Knight's tactic, he won't have an advantage in positioning casters and archers; Armored Warriors or Zealots can protect us from Centaurs and Cyclops (throwing Goblins)!

Take a look at a replay of a duel preset built according to this scheme – it clearly shows how Cyclops are excellent at tearing apart such "boxes" with casters and archers, protected by defensive units. Against Cyclops, it is better to try to spread out the troops across the field, which is often impossible.

The situation is clearly not in the Orc's favor, IF he has an initiative advantage, then the Cyclops will quickly come to us(((but you can sacrifice Griffins to block the approach to the main troops!

But I think the opposite is true. :)
By the way, Griffins will be nerfed in initiative with Storm Wind, and they are not good as blockers – they are crushed like paper.
