So I haven't picked up this deck in a while, and even when I did I wasn't sure if it was going to survive rotation. All the madness cards are gone and that subtracts from what the Fiend can do...
So a few updates:
Lightning Strike was an easy include. It's been a staple for burn before, and I'm sure it will be again. 3 damage, 2 mana, instant speed- yep.
Magma Spray is a nod to the return of the Llanowar Elves. I'm not sure if I'll keep it the spray, or perhaps switch to the shock, only testing will tell.
The Flame of Keld is another card I've been testing with. It fits the discard theme, gives a bit of boost in the card draw department, and the damage boost is nice too. One of the problems I mentioned earlier was falling behind on cards, and this helps with that a bit. Typically by the time I'm ready to cast it, I'm low on cards already. I don't usually lose too many\ any cards to it. It's a better top deck than the Cathartic Reunion, and it also combo's well with the Bomat Courier. So far in testing, I've discovered that if I have the Key to the City I'm discarding the Flame.
Also, a corner niche is playing the Flame with the Fiend on the table and a few cards in hand- can sweep the board.
The Soul-Scar Mage is a solid 1 drop that benefits from all the spells we're casting, and also provides an option for dealing with indestructible creatures.
And the Field of Ruin is a necessary evil for all the flip and utility lands in the field right now.
Even with all the changes, the deck is showing at under $79.00- and most of that is the mana base.
