Blood Witch Gretta

Blood Witch Gretta is a boss that can be encountered during the Monster Hunt.

Deck
The below classes are listed purely for reference, and have no effect on the boss' use of the cards during the battle.

All
If Gretta opens early with Mistress of Mixtures it's a good time to play spells if you have a minion out capable of killing that turn, particularly if you have not already damaged Gretta, as she won't benefit from the healing but you will.

Gretta will make use of Violet Illusionist to prevent taking damage from casting spells, so destroying the illusionist should be a priority to prevent "free" spells.

Darius Crowley
Having barely any spell, you will need to survive an onslaught of spells. If you can build a board, you will win

Houndmaster Shaw
Typically your deck would be light on spells but powerful cards like Call of the Wild can make for a very quick game.

Toki, Time-Tinker
If you can obtain a copy of Violet Illusionist then most Toki decks can do a better job than the boss can with infinite Mana. If Archmage Antonidas has been, the boss should be pretty easy to defeat.

Tess Greymane
Early in the match, prior to any spells being cast, using Tess's hero power to generate 0-cost A Small Rock can be useful, since it won't cost you Health.

As with Toki, obtaining a copy of the bosses Violet Illusionist can end the game in a heartbeat. You can use your hero power to obtain copies of her Mirror Entity and hope she plays the right minion but a better way of obtaining it is through Gang Up which appears alot in card packs along the Monster Hunt. The passive treasure Cult of the Wolf is very useful here as anything you get is going to be castable right away most of the time.
