Combo burn/control deck. They're my favorite type of decks, so I decided to make one that has both.
----------------------------- Mainboard ---------------------------------------------
Goblin Electromancer is a great card. 2 drop for a 2/2 AND chops down the mana costs of my spells? Fantastic.
Spellheart Chimera is great for attacking with the amount of instants and sorceries in this deck.
Ral Zarek can be used for all his effects. +1: Tap an opponent's creature if you need to swing, or maybe their land just in case you think they may have counter spells. You can use the second part to untap your land for more mana usage. -2: Burn. -7: Who doesn't love extra turns? I may not use this much, but it'd be nice if I'm feeling lucky.
Keranos, God of Storms's mana drop is a bit much, I know, but it's just too good to pass up. It's either draw power, or burn. It's great.
----------------------------- Sideboard ---------------------------------------------
Counterflux for going up against control.
Turn / Burn
for creatures that are hard to kill.
Mizzium Mortars & Anger of the Gods for those nasty heavy creature based decks.
Negate for heavy noncreature spell decks.
