This question came up at at another forum and...well...I have a little more respect for the opinions here, so I thought I'd bring it up. We love debate here anyway. 
Obviously Panther Warrior cannot tribute itself and then attack because it would no longer be on the field. But can it tribute itself just because? Might make a difference. Might not. But that's the kind of questions we like around here.
Also, what's Panther Warrior's effect, Continuous or Multi-Trigger? I thought Ignition as first but then, I can't think of another Ignition Effect that can (or has to) be activated during the battle phase.
Peace
