I was going some GC planning so I started adding upgrade costs.

My hope is 333333 (18/29) is enough to win the event, that's 263GC, so 163GC net for the event. Not bad, if true.

If that's not enough, then 633333 (21/29) will almost certainly be enough if special event precedent is any guide. That's 383GC, so 283GC net. While the E4 upgrade is the most expensive level 4 upgrade, there are two R$ upgrades after it which makes it the cheapest path to 21 upgrades.
