How Steel Your Heart plays

Steel Your Heart is A tier over all champions on patch 26.21: #26 of 226 augments and #9 of the 90 gold cards. That is the average over every champion; on the right one it is worth more, on the wrong one much less.

It does best on Sion, Sett and Diana. 8 of its 15 best champions are tanks.

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

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