Fanatic of Mogis ?

jedrzejmk he is in the sideboard. He is a big card and I would prefer the ancient because he a is HUGE threat and adds devotion for nykthos.

I would switch Shock s for him. They rarely remove anything useful and you'll get more damage through mogis.

the Shock 's do help for early removal/life loss. It's good to get when you have 3 lands (assuming you missed land drops) and you are just top-decking. mogis is not the win condition, because i do not have all the devotion creatures like Frostburn Weird and Ash Zealot .If I went the devotion route I would have mogis main board with 2 or 4 of them (I don't like 3-of's). But since I am doing burn over devotion, I prefer the shock.

However mogis would be amazing if he had haste. At that point I would but him in. He would be the Hellrider sub.

Fanatic of Mogis with Hammer of Purphoros then :P It negates land top decks as useless and gives haste for your fanatic + devotion.

Since you're running white, why not Soldier of the Pantheon instead of Firedrinker Satyr ? Gain life instead of lose it, same power, toughness, and cost and also some protection. Also, Young Pyromancer is fun, but if you want full on aggro then i'd probably drop it for Chandra's Phoenix for a repeatable creature that benefits from you casting your burn spells.
