Your nuts, it cost way more to use N cards. the way I suggested only cost about 500K, assuming you have 6 F+. Also that chart is incorrect, cost to fuse does not increase by 200, as you go up in level so does the cost per card. example: at lvl 5, cost to fuse 1 card might be 200, but at lvl 15 cost to fuse that same card would be about 1200.
