How Master of Duality plays

Master of Duality is B tier over all champions on patch 26.21: #124 of 226 augments and #42 of the 69 prismatic cards. That is the average over every champion; on the right one it is worth more, on the wrong one much less.

It gives ability power, attack damage and attack speed, so it pays off on champions that already use those. On a champion that doesn't, it is a wasted pick, whatever its tier.

It does best on Xin Zhao, Kayle and Yunara. 6 of its 15 best champions are fighters.

Its tier holds in every pick it can show up in (B tier), so there is no bad moment to take it.

The card it pairs with best is Tap Dancer: if you already have one of the two, the other jumps up your list.
