Rulings:
1. The triggered effect can still be used even if the card is taxed since its cost doesn't require taxing the card to activate its effect.

2. The previous ruling of this card allowed its counters to go on lords, this is no longer the case. - STZO/STZO SE
3. The previous version also was not mythic or have a triggered effect. - STZO/STZO SE
