One ruling from Wizards of the Coast
- 1 May 2008You put the -1/-1 counter on Cinderhaze Wretch as a cost. That means it happens when you activate the ability, not when it resolves. If paying the cost causes the creature to have 0 toughness, it’s put into the graveyard before you can untap it and before you can even pay the cost again.
