Ajani, Nacatl Pariah // Ajani, Nacatl Avenger
Legendary Creature — Cat Warrior // Legendary Planeswalker — Ajani
Rulings (15)
If you are instructed to put a card that isn't a double-faced card onto the battlefield transformed, it will not enter the battlefield at all. In that case, it stays in the zone it was previously in. For example, if a single-faced card is a copy of Ral, Monsoon Mage, choosing to exile that permanent during the resolution of its triggered ability will cause it to remain in exile.
The back face of a transforming double-faced card usually has a color indicator that defines its color. Colorless back faces, such as lands, do not.
In a case where you create more than one Cat Warrior creature token with Ajani, Nacatl Avenger's second ability (for example, because of the effect of Doubling Season), the reflexive ability will trigger once for each Cat Warrior you made this way. If a replacement effect causes you to create different tokens instead (for example, the effect of Divine Visitation), the creation of those tokens won't cause the reflexive ability to trigger.
