geniuses are actually the most expensive way to skill up a card. 20 per? following your plan, youre looking at around 75 ED just for one attempt, and still can fail 1 out of 4 tries.

or, you can buy junks. paying high at 1 to 1, youd still have enough for almost 4 tries. sure, its only 40% using rare ex, but oh well. usual price is about 3 for 2. at that rate, 3 tries for 40. 6 tries for 80. if youre lucky, you could find rates at around 2 for 1.

another option is to try buying imperfect rares. if youre lucky, you can find some for pretty cheap, with an enhanced skill level. higher skill level of the sacrifice will increase the gain. from them. (in this case, an sk8 rare ex would add 18% by itself.)

but, after typing all this up, maybe your plan isnt a bad idea when trying sk10. but, i do know of one last way, and is the most cost efficient, but its only possible at certain times and is also wasteful for different reasons, thus i dont even do it.
