I can't really discuss that without revealing some incredibly broken picks. But suffice to say, there's some very powerful characters with tricks that are unique or hard to defend against in anime/manga. Some of them are one trick ponies, but the one trick is very good.
For an example; a few years ago during one of Delph's tournaments. I picked up someone named Jotaro Kujo. Look him up. I had to use some very sneaky reasoning and forfeit rights to use certain feats to get him in. I WILL be looking for people trying to do that. So if you want to try something like I did, you'll have to convince me.
And given that I am the forum champion of sneaking dubious picks into tournaments semi-legally, 😂, you're welcome to try. I did try to get the Worlogog in prep, afterall. flirt So I have a fair idea what to look for.
