I have updated the cards in the deck list to reflect the changes that I have currently made. I took the previous iteration to my LGS standard tournament, and the only win I got was from a second round bye...
The lifegain aspect of the deck worked great early game, however, mid game the creatures lost the ability to punch through defences and I found myself 2 for 1'ing my opponents creatures to either keep my creatures alive or to prevent me from taking massive damage. By turn 6 or so I literally was running out of gas, even with the Pyromancer's Goggles copying all the instant spells. So here were the changes I made...
-4 Dawnbringer Charioteers for +4 Ajani's Pridemate. With all the lifegain, the Pridemate will grow into a larger creature and either swing in for more damage or cause removal to be used on it.
-4 Fall of the Hammer and -2 Tail Slash I was using these as my removal spells as they worked with lifelink and also triggered heroic on the now gone Charioteers.
+2 Chandra, Pyromaster. She will provide me with either a means to attack without being blocked, pseudo card draw, or removal fodder, giving me extra time to find a win.
+4 Tormenting Voice hopefully this will give me some much needed card draw to keep my hand full of fuel. I prefer to use this spell copied with the Goggle to net me 4 cards per cast.
+2 Sunscorch Regent I added this to help against flying creatures. Also, when my opponent casts a spell the Regent gets bigger and the lifegain it provides also triggers the Pridemate.
+1 Volcanic Vision Added as a 1 of due to its high mana cost, it's here because if I can cast it with the Goggles I can recur 2 instant/sorceries from my graveyard and deal damage based on its CMC. If I grab back a Stoke then it is 8 damage, Anger is worth 6.
Wind-Scarred Crag was added as a 4 of. Normally, I don't think that I would want any more comes into play tapped lands, however, they do provide an instance of lifegain that can also trigger a +1/+1 counter on Pridemate.
