75 Mythril worth of luckies was fair.
Imperil - SSB's for Balthier (Fire) and Edea (Dark). My only imperils are already for these elements, and I have BSB imperils. Extra 10 MAG for Edea (very strong BSB) is the takeaway.
Medica - Yuna SSB2 (curaga + 2k hp stock) is nice to add to her BSB2, Relm SSB (dupe), Yuna USB (curaga, reraise, last stand, haste), Penelo USB (instant, phys blink, 2k hp stock). Definitely adds to full throttle capabilities for Yuna and Penelo (both with BSB MAG/MND buffs)
BSB+ - Exdeath (imperil dark, lols), dupe Tidus CSB, Vaan OSB (full throttle/finisher with his BSB), Lenna USB (ATK/MAG/RES buff, 3k hp stock).
Basically for 75 mythril, I got a lot of healing stuff and two different stacking buffs. For 5 disco balls I didn't get much, but sheer quantity of relics was a great value @ 75 mythril.
