There was a response to this statement before. Plus, trump cards are not standard units, and they cannot be produced every week. But level 7 units are ELITE SOLDIERS!

I want to disagree with you. Elite *soldiers*. These can be inquisitors, vampire lords, liches, ents, etc. According to your logic, there can be no "trump" units at all, since they are not even supposed to be produced. Level 7 is precisely the trump units, and they have every right to be called that. That's why they are not produced in large numbers and do not cost a penny. ;)

Now regarding a candidate for the role of a level 7 creature... hmm... I'm not for the hippopotamus, but against the troll. It would also be silly for champions to stand out among the higher-level creatures in the Fourth part. You know, maybe I'm also tired of dragons in all the parts, but I'm suggesting replacing them with minotaurs. ;) And to argue that these are some special minotaurs that also ate Greeks in labyrinths :p
