Deck Insights:
AEtherling: Good finisher if I'm struggling to finish off my opponents life total, and a great blocker if I need him. Overall one of my favorite cards in magic.
Chandra, Pyromaster: Excellent for letting me see an extra card every turn, and helping search out land if I need it, along with clearing blockers and pulling Chandra's Phoenix back from the graveyard. Her -7 can be a game winner as well.
Chandra's Phoenix: Persistent overhead attacker who I wouldn't mind using to block because of it's synergy with Chandra, Pyromaster and all of the burn spell. Also an easy discard if needed, for the same reason.
Guttersnipe: Helps add some extra pain to the burn.
Flamespeaker Adept: With all of the Scry in this deck, it's nice to let it get buffed up and gain first strike when I drop a temple, or cast Dissolve, Magma Jet, etc.
Mizzium Mortars: Helps as a board clearer if I need it, I may take it out however, as it can only target creatures, and not at instant speed. If I take it out, it'll get replaced with Cyclonic Rift, most likely.
Curse of the Swine: Oh, is that a Consuming Aberration? Here, have a pig.
Steam Augury: Some more card draw, and fuel for Spellheart Chimera.
Spellheart Chimera: With 26 instants and sorceries, there's a lot of fuel for it's power, the only thing I wish it had was more than 3 toughness. Still great for damage because of flying and even if you block it, chances are trample will cause you to take some still.
Magma Jet, Shock, Lightning Strike: Good, old fashioned burn that can help put Chandra's Phoenix back onto the battlefield if needed.
Temple of Silence, Temple of Abandon, Temple of Deceit, Temple of Mystery: Scry for Flamespeaker Adept.
Stymied Hopes: I don't like letting people pay there way out of counterspells, but it has Scry so it slips into the deck.
