save your stratergy item packs every day. i have a stack of about 30 at the moment and counting, mut leaks just leaked blue strat items.
i always save these when we are at the green level as these do update to include blue when they release. have done it every year and pull blue strats with saved stratergy packs!
the ones like in the zone etc go for a lot of coins on the first few days, a lot of coins to be made. also always buy green stratergy items on the AH if they’re listed for 11k or less as it’s a 1k max investment for sets :)
