Please Note: I do not play PvP, nor do I spend money on packs, thus I do not have all the cards that could benefit this deck further.
This deck is pretty self-explanatory, but here are the basics; Getting a lot of your weaker Wisps into the graveyard to buff
Umbren Deathwatcher. With your Wisps being sent to the graveyard often you'll be active a lot of tribute abilities, more importantly that of
Mistress of Light.
With this deck, I found myself a lot of the time relying heavily on
Illumination Wisp and
Blistersting Wasp, but they get the job done, and that is what is important.
