Planeswalker Challenge - Ablaze (Casual)

Created for the Planeswalker Challenge - build a deck for any Planeswalker that is thematic, fun to play and accessible.

The simple rules of the challenge:

1. Choose your Planeswalker.
2. Your deck must include 3 copies of that Planeswalker (or, for those that already have theme decks, you can include 1 copy of that Planeswalker and the 2 cards from that deck that tutor that Planeswalker).
3. Your deck cannot include other Mythic cards, and can only include up to 4 Rare and 16 Uncommon.
4. Your deck can only include cards from the same block (or set, post-blocks) as your Planeswalker.

The guidelines for the challenge:

1. Try to create a deck that really shows off what your Planeswalker can do, and that suits their personality.
2. Try to stick to a colour identity that is thematic for your Planeswalker.
3. If your Planeswalker is aligned with a particular faction, try to include only cards from that faction and 'neutral' cards, not cards from other factions.

About this deck:
Chandra's +1 ability basically allows her to turn any red card into a 0 mana Exquisite Firecraft to rearrange her opponent's face every turn. At the point in the game when you can summon her, you probably need to go big or go home, so this deck is designed to make that possible.
This deck tries to double down on the theme of setting fire to whatever you want, with Burst Lightning, Punishing Fire, Staggershock and Cunning Sparkmage all allowing you to get some early damage in (remember that you can tap the Sparkmage after blocking with it, if you have to use it as a blocker). Then there are the cards which benefit from that strategy: Quest for Pure Flame and Kiln Fiend, which allow you to get some big spikes of damage in. Chain Reaction can create some breathing space when you most need it.
Try to make the most of the opportunity created by a timely Smoldering Spires, and when you summon Chandra she'll only have mopping up to do.
