Higher AP PVP Battles, and Circe is OP?!

I hope all of you know that Attack Power (AP) doesn't actually matter a whole lot, I fought two 290-300k opponents (with my 273k army) and won both stages.

Here was the easier battle:
(as an interesting part of this battle I discovered Terim's dragon could tank Robinhood's skill, which may be a good or bad thing. If it tanks it it will die super quickly, but on the bright side it's not a very important hero to lose... ¯\_(ツ)_/¯)

I have a couple of strategies I use for these battles.

First of all, make sure all units correspond to strengths and weaknesses properly. I always make sure I have all the strengths and weaknesses planned out so I can deal maximum damage while taking minimum damage.

Another key part is to use your rally effectively. A little strategy goes a long way, and never underestimate the power of any four-star hero (yes, even heroes like Charles Martel, Anatole, or Ragnar, although that doesn't happen as often)

Here was the 300k AP battle:

I found a couple things were very effective in this battle.

First of all, I moved my tanks around so Reinhard had less to deal with and therefore Philinus and Terim weren't overrun. Overloading a single hero can result in failure.

Secondly, I got an early edge when Einar and Sarky tore through their rows. I find an early edge is very useful (if it doesn't happen, use morale skills to turn the balance of the battle back into your favor)

Thirdly, Charles the Great was placed in a row where he would take a lot of damage and therefore spawn his second squad in, which helped greatly in tanking for that row.

Fourth, Choe Yeong survived for the entire battle, and was able to get many skill procs in, allowing maximum troop spawnage.

Fifth, Circe was important, as she cloned some of his best heroes (cloning Bellerophon allowed me to get extra troops--they don't disappear when the illusion disappears :D)

And finally, I used some rows to stall enemies, effectively blocking his damage rows until my other rows could get to attacking them.

Here are some stats from the battle:
Einar and Sarky, doing their usual AOE damage, with Circe's illusion (she cloned enemy AOE heroes) doing a close third. CTG's second squad counts toward hero's damage dealt, so that's why he ranks pretty high up.

Philinus did a very good job keeping Reinhard alive:
Leonidas healed a lot because of his hero emblem (which I have up to third tier)

Jerome really surprised me, dealing more damage than Ignatius! I'm surprised Achilles didn't make it on this list, I forgot what happened to him. Mages a really good with damage, and musketeers (Sarky at the bottom) don't do too bad either.

And I'm beginning to notice a trend. Circe's cloning ability can be very good if the opponent has a hero that summons extra minions, especially Charles the Great. If the enemy has a 5-star hero emblem upgrade on CTG, couldn't Circe cloning him effectively spawn in 3 squads of cavalry?

Note, that is for every proc, I have seen Circe proc very often (twice in three seconds)

Therefore, you could use (or abuse) this ability to summon in 150 extra troops by cloning an enemy CTG.

These new unit-summoning heroes just found their weakness.

Circe is a great hero in that aspect, she can use any enemy ability against them. (cloning Merlin was great)

I could foresee a way to counter unit-spawning rallies through this.
