LF Maps with Warhound units

I am looking for maps where I can make warhound units. Warhounds are terran mech units that were suppose to be added on Heart of the Swarm. However, they were too powerful they got banned before the game was released.

I am not looking for anything fancy; just whatever ladder maps where the option to create warhounds is available. It will be better if it was for Legacy of the Void since I also want to build those units. 2v2 or 3v3 ladder maps would be awesome. If anyone has those custom maps and wanna make them please share them with me
