Creature â Hydra Hound
As Hydradoodle enters the battlefield, roll X six-sided dice. Hydradoodle enters the battlefield with a number of +1/+1 counters on it equal to the total of those results.
You can choose 0 as the value of X. However, you wonâ€™t roll any dice as it enters and it will be a 0/0. Unless something else is raising its toughness, it will be put into its ownerâ€™s graveyard.
