Yeah, that is very expensive, but there are plenty of affordable items that you can get from just betting, or tournaments and daily logins. Customising your tori is nice, but it isn't essential, so I don't really care about the fact there are a few ridiculously expensive items. Some people who duel or host bet servers earn huge amounts of tc, and it is important for the game to have some expensive items for people like that to spend their tc on.
