Seeing this recent TFT Clips video about Double Trouble Taliyah reroll got me thinking.

DT3 elevates Taliyah reroll from decent to an OP comp that almost beat this 3* Azir Lux if capped.

What other augments elevates a comp like that? or even makes a comp viable (like those transformative hero augments for WW, Sett, Kassadin, Swain, and Galio carry).
