The resource doesn't have to be Heat. Competitors can make their champion use Fury as a resource, for instance. As long as the kit has low-cooldown basic abilities which, if 'spammed' too much, their cooldowns, costs, damage, etc. are increased, the competitor's entry should qualify.

tl;dr If X champion casts Y within the next 4 seconds after previously using Y, Y's cooldown, cost and damage is increased by Z%. This stacks up to ? times.
