The order as shown in Sandbox is Red, Blue, Green, Yellow, Pink, Black, Purple, White, Zebra, Lead, Rainbow, Ceramic, MOAB, BFB, ZOMG, DDT, BAD.

So that means (if Mastery existed), then Round 40 is a BFB, Round 63 is 122 MOABS stacked and 75 Rainbows, Round 80 would be 1 DDT, 95 would be a whole bunch of BADs, 98 would have fortified BADs, and 100 is a Boosted BAD with 40000 health.
