Dominion
it has many annoying qualities for pvp and can be used in this pve situation

Artifacts:
helm of dominion is a must
you want to be able to take her more powerful creatures
at least 1 or 2

Spell:
assassinate is also needed
you need to be able to take out her weaker creatures that can steal health
at least 4 (you want the maximum)

Creature:
moon priestess is optional
she is very helpful but can be opted out if need be
at least 1

shadowstep assassin
there helpful for taking out powerful creatures
at least 2 to 4

blood born prince
very helpful but you'll need some useless things for it to be
2 to 4

spoiled aristocrat
useful for his uselessness i
i generally use him to power up blood born prince
at least 2

Dreyla, ruthless opresser
optional but at the same time, not
incredibly helpful and evn better than helm of dominion, if you last long enough to use her propperly
at most 1
she's a bit difficult to get out and use properly
(be sure to move her to support line so she can't be targeted)


as for the rest of the deck
just use the standard starter stuff


if anyone has beaten her with anyother deck please do your best to describe it below

you have to kill the little ones that take health as fast as possible so use assassinate or shadow step assassin (but only use the creature to block and only when absolutely necassary)
the ones that fly in the back you have to take control of quickly as well ( helm of dominion or dreya)

practice the game for a bit
don't know about anyone else but i was level 11 before i could even scratch her
get the hang of how to play and used to the deck you use
i've barely beaten her twice so dont get frustrated (at least not too much) and remember
its an AI
you can cuss it out as much as you like but she can't hear you


hope this helped
special thanks to Thomas who gave some of this advice to me
