I played a little bit more against Mono G stomp: 4-4

I won when he didn't play 1-2 mana creatures, so I could rush him to death before he did. His deck is filled with creatures, I can't afford to waste damage on them. A boardwipe would be nice, but his creatures are quite resilient thanks to Undying (Strangleroot Geist) or power-ups (like Vines of Vastwood). Searing Blaze should be good, but I never draw it in 8 matches.

Overall, it is a balanced matchup, strongly dependent on each player's initial hand.

What I learned from this tournament:

Lightning Berserker is bad, I never played it and it wouldn't be useful in many situations. Removed.

I need more fetchlands: I lost a couple of games because I draw too many lands. I probably need at least 8, and 2 Stomping Grounds.

I obviously need 4 Goblin Guide to replace 4 Spark Elemental: it must be in my deck, it can win games in 3 turns with some good spells to support it.

I never really used Destructive Revelry: I have it in sideboard against Leyline of Sanctity, but no one played it.

I'm considering Atarka's Command: deals 3 damage, prevents lifegain and buffs creatures (buffs Monastery Swiftspear twice), it is a sidegrade to Skullcrack.

I'm also considering Molten Rain instead of Blood Moon: Blood Moon gets easily removed in many situations (Nature's Claim, Oblivion Stone, ...), but, against someone with no answers to it, it can give you victory.

Splash for Atarka's Command, it's incredibly powerful. I play the full modern burn list and it can do some serious damage.

Nixin72 - Yes, I'm playtesting it and it allows many turn 3 wins (e.g. with 3 Goblin Guide/Monastery Swiftspear, Atarka's Command and any 3 damage spell). I probably will sideboard 2 Skullcrack and remove 2 Magma Jet or 2 Shard Volley to use it.

I would drop Collateral Damage and Magma Jet. Magma jet is the lowest impact burn spell and collateral damage is the one with the greatest negative impact on you. Leave the 4 Skullcrack in since you aren't playing white.
