Chandra, Acolyte of Flame

You must pay the costs for the spell you wish to cast with Chandra’s last ability. If that spell has any alternative costs, you may pay those.

If a card in your graveyard has {X} in its mana cost, X is considered to be 0 while you target it with Chandra’s last ability; however, once you begin to cast it, you choose a value for X. If this causes the mana value to become greater than 3, you can still cast the spell.

Chandra’s first ability will put a counter on herself as well as any other red planeswalkers you control. This doesn’t cause any other planeswalkers’ loyalty abilities to be activated.
