When both Dread Hound and Terror Hound are in a team, creatures seem to only have one stack of dire wolves when attacking instead of 4 on the first turn. It seems like Dread Hound might be setting the stacks to one instead of adding one stack.
Thank you for the info!
As a follow up to this, when my creatures were affected by the red orb (your creatures attack at the start of battle), three triggers of dire wolves went off. Which makes me think Dread Hound’s Summon the Pack trait is the culprit in this case.
