Are there other Trickster gods in Asgardian mythos?
Loki
Loki is referred to in the Poetic Edda, compiled in the 13th century from earlier traditional sources; the Prose Edda and Heimskringla, written in the 13th century by Snorri Sturluson; the Norwegian Rune Poems, in the poetry of skalds, and in Scandinavian folklore. Loki may be depicted on the Snaptun Stone, the Kirkby Stephen Stone, and the Gosforth Cross. Loki's origins and role in Norse mythology, which some scholars have described as that of a trickster god, have been much debated by scholars. Loki has been depicted in or is referenced in a variety of media in modern popular culture.
Trickster (comics)
In September 2011, The New 52 rebooted DC's continuity. In this new timeline, Trickster/Axel Walker is reintroduced as a member of the Black Razors, the team responsible for dealing with the Daemonites invasion. He is tasked to work alongside Priscilla Kitaen in order to take down her clone. He is later seen as a part of Glider's Rogues, and rescued Captain Cold, and attempted to reason with an invading Gorilla Grodd, which led to him losing his right arm. He later was equipped with a robotic arm which essentially functioned like a normal human arm.
