I like how you guys undercharge stuff that's much harder to find then even-useful cards. Look at the drop rate: Old Violet Box [0.14%] , Old Blue Box [0.12%] . From ninetail, the most easily farmable obb source of 30% obb/kill and the 0.12% drop from obb, that's roughly 2777.77 ninetails for one emp anvil. By the time you get one of them, you'd have obtained 8-9 cards. While ninetail card isnt exactly useful, even if you go and farm otherwise useful cards like say ray, you'd have obtained at least 4-5 cards for the time needed to farm and anvil. Factoring in the crapload of zeny everyone can easily obtain, I'd say it's CHEAP to sell them at 10m. Lucky to whatever bum you sold it to for 1m.
so if alarm mask takes 3000 clock hands which is like getting 9 cards, it must therefore be CHEAP to sell it at 10m factoring in the crapload of zeny everyone can easily obtain
just because something is hard to get, doesn't mean it's worth more.
