I've got 149 Legos now, rest skulls.
I'm keeping me elix full all the time since I'm currently pushing and once I'm full, I'll do another wall. Not even bothering upgrading them with gold since there are still valuable things to upgrade with it - ATs and later cannons as well (just three ATs to 13 left).
I have one builder free all the time (or often two), but I don't care really... better I can use my resource whenever I need to instead of sitting on stupid full storages for longer than a day.
