Magic. Draik MPs are really hard to get though, they usually get bought up within the second they restock. You have to be really lucky to get any good MP from magic, really.
lev isnt even close to the most profitable thing to restock... theres ttear, emerald eyrie coin, mastermind plushie, glittery scorchstone, and thats all off the top of my head tear is 40m, eec is over 70, mm plush is over 40, and glittery ss is around 200 as for most expensive that commonly restock, draik or krawk mps, draik eggs, bgc
there is only 1 of them in existance...and it will never be for sale, if another one ever stocks there are many who would pay 200 mil for it just to collect
