Maximal here, numerous time legend and vivid handlock player. This is my take on Elemental Handlock.
Igneous Elemental increases hand size while also stalling the game a little bit and provides a couple cheap elemental activators.
Tar Creeper Tol'vir Stoneshaper Tar Lurker act as additional taunts to stop aggro decks.
Frozen Crusher Not sure it’s good enough, but this is one of the few deck archetypes, where this card might see play and is a possibility. Acts as Mountain Giant of sorts to apply pressure against control decks. Can be taunted up, can be used as a shadowflame target for huge board clear and acts as an activator for Blazecaller. The card is a meta call.
