How Shrink Engine plays

Shrink Engine is B tier over all champions on patch 26.21: #92 of 226 augments and #31 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 gives ability haste and movement 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 Shaco, Nami and Milio. 11 of its 15 best champions are supports.

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 Terrain'd: if you already have one of the two, the other jumps up your list.
