Ok so if anyone cares il be giving a review regarding the medium damage hitters in terms of tiers:
If youre still bot able to reach the highers tiers then shakkoumon is the best out off all off them. He has the highest stat total and is the tankiest out of the 4. The only tradeoff here is that he has the lowest attackstat out of the 4 but the difference is not very large. But the trafeoff is that hes not the most efficient out of the 4 and requires the most time along with zeedmillenium. Another possible tradeoff may be that hes 2-4 and not 1-3-5 like the rest. That could impact hos tower popularity because the 1 turn in the damage reduction skill can be a big deal, but nothing is confirmed yet.
Second comes zeedmillenium. The reason he is number 2 is because his defence comes second and he has the great damage reduce ability that is valueable in tower. His event was pretty big and not that efficient but all in all the card is not bad, just (sadly) not as good as shakkou. But if shakkou is 2-4 and not 1-3-5 then milleniummon is the best option for tower out of shakkou and Imp PM because his skill is fast and him being of the dark race thus his attacks not being resisted by anything.
Ofanimon was the SP reward for PvP so in a sense she was "free" for most players and at the time the best 1 turn medium hitter was daipen so she was a huge improvement, but she has fallen somewhat a bit down the list, still great card, dont get me wrong. She will always have a special place in our heart and im sure lots of people runed her.
Last comes Victorygreymon. The thing with him is that his defence is the lowest out of the 4, he has a decent health stat and has by far the most attack damage, but that doesnt make such a huger difference. His only edge that he has over others is that he can be used in combination with Imp FM from the PvP SP reward to boost his attack further or with a vikarala comp.
His upside kinda us that his event was not as large as shakou and millenium due to the event being just a regular one despite being SP like the rest, although you didnt get a free copy to make. But hey, 20 caps more then the regular 100 is nothing in cpoarison to 240 minus 20 for shakkoumon and the 400+ caps or so for Zeedmillenium. And there was even a big for IOS where it would be possible for the SP egg to drop. But lets not further talk about that...
