How Overflow plays

Overflow is A tier over all champions on patch 26.21: #74 of 226 augments and #22 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 Ryze, Ezreal and Fiddlesticks. 6 of its 15 best champions are mages.

It is stronger early: A tier as a first pick and B tier by the fourth pick. Take it when it shows up early.

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