Without the visual aid it would have been impossible to notice. Instead of exiling 5 cards as suggested by the card’s text, it only exiles 2 cards from my opponent’s graveyard. Please fix.
Were there more than 2 cards in your opponent’s graveyard? Just checking, I don’t doubt that its bugged
Most definitely “yes”! I’ve cast it multiple times to get rid of the lifelink Vampire that returns whenever my opponent surveils. The visual aid says -2 from graveyard, More than 0 cards still left in the yard.
They seem to be sort of rebalancing cards vs effect then forgetting to patch either effective code or the text of the card. There are numerous cards that give stuff different from what’s written, sadly I don’t know how to play de-localized version of the app, or to retrieve english names for them 
say one 6-mana draw 3 cards lose 2 life makes player lose 3 life instead. Most likely this one is also a victim of such a treatment.
