Viven's Grizzly Bug Disappearing Cards
Oracle Text of Vivien's Grizzly
3Green: Look at the top card of your library. If it's a creature or planeswalker card, you may reveal it and put it into your hand. If you don't put the card into your hand, put it on the bottom of your library.
Issue on Magic Online - Activate Grizzly, creature is not revealed. Card disappears from game, deck count reduces by 1.
How this should work - Card is placed on bottom of library, deck count should remain the same.
But Reimbursement Request isnt resolve the functionality of the card!
