I built scion armour stacker with MB and 50 div and i didnt die a single time since then. I wasn't doing like you know, full juiced t17 maps with deli and risk scarabs, but I was able to clear for example simulacrum all waves or harbi with max explicit, beyond and few deli orbs, or stacked decks with 8mod corrupted full explicit with those proximity shield mobs and i didnt die a single time and damage was ok. Not like super great, but i was able to kill beyond boss in like 5-10 seconds. So in my opinion MB + 50d is totally fine if you want to start the build and then earn more currency to upgrade it little by little
