Toxic Spikes users greatly improve the effectiveness of this set as most of Suicune's counters are vulnerable to them. Specifically, Pokemon that can wall Suicune's mono-attacking coverage or power or that are otherwise unthreatened by its power, such as Jellicent, Blissey, and Quagsire, all fall to Toxic Spikes. Pokemon that can form a Fire / Water / Grass core with Suicune have excellent defensive synergy with it and are thus excellent partners. Examples of this include Mega Venusaur, Ferrothorn, and Heatran. For a more offensive approach, Pursuit users such as Tyranitar, Scizor, and Weavile can eliminate Jellicent and Celebi, two of Suicune's best counters. Scizor is also notable for being able to scare out or OHKO Celebi with its powerful U-turn. Alternatively, one can run Suicune alongside wallbreakers such as Kyurem-B and Hydreigon, which can wear down Suicune's checks and set up a late-game Suicune sweep.
