Gloo

In teamfights, Gloo can use his 1st + 2nd skill combo to close in on the enemy and immobilize them. Then his 1st Skill and Ultimate to add more Sticky stacks to enemy heroes, and attach himself with his Ultimate to the enemy hero with max Sticky stacks. Once ready, Gloo can use the combo to deal damage and move the host out of position. Finally, he can use the refreshed 1st Skill and his Basic Attacks to finish off the host.

In the laning phase, Gloo should use his 1st Skill to attack the target enemy and create a Goo, then he can use his 2nd Skill to target the Goo to bring the target to its location and trigger an explosion. Touching the Goo will also reset Gloo's 1st Skill, allowing him to use it again to deal damage.
