this card is balanced in 1v1, but absurdly unfair for dexterity arena decks. you dont get to draw cards, at all. good luck winning with your first 7 cards, especially if they keep getting bounced back to the top of your deck (that you will never draw again). even the mercy limit of two (like silence) would not fix this, as the loss of tempo from even one is devastating against decks that always combo it with rewind and steal. the only deck that had an advantage against ghostmare was pharaoh SoR combo. the AI would target the cheap scarabs and your deck naturally had enough time quantum to fight against GoTP. thanks to the quantum nerf on shards and the SoR nerf...now everyone gets owned by this frustrating and lame deck again. meanwhile, its not a strong deck against the AI, as your lack of card advantage causes your theme to be either too weak or too late.
just another card that rarely makes it in player decks but you get hammered by it constantly. if rush decks were viable its an honorable mention as a 1-of to jam your opponent a card draw and gain enough life to win...but those kinds of decks are poor against plat these days.
remove the card from the game, or change it to something that doesnt auto-win when the AI spams it every turn
