Hearthguards is an epic dwarf unit that gains strength if it is played next to a structure. The initial strength of Hearthguards and the amount of strength it gains can be increased by leveling it up. Hearthguards works well in structure decks.
Without structures in your deck, Hearthguards can be just a costlier version of Bluesail Raiders.
Cheap structures like Fort of Ebonrock can be combined with Hearthguards to create a 9 mana, 6 strength combo. It's comparable to Olf the Hammer, but missing an important ability.
Hearthguards is good at protecting important structures with its ability by gaining strength and having 2 movement.
You can also play Hearthguards to set up a strong front with its combination of 2 movement and high strength.
If there are a lot of units near your base, playing Hearthguards can take care of it well.
