Gruul Aggro Value (EDH / Commander) [Révision 22]

So I struggle to built straight aggro decks, this seemed like a good opportunity to build an aggro deck as a value player because I need to attack to get the value.
I run a really tight mana curve, lots of elves that can attack for my commander to trigger but can also tap for mana if I need ramp instead of card draw. Running such a low curve means I can quickly play out all my good cards allowing me to trigger Galia as soon as possible. Secondly, I've tried to make Squee my secret commander, the Matron can search him and in theory I can play out my hand, including creatures that give me extra land drops so that Squee is the only card left for me to discard.
The decks biggest weakness is an excess of mana which can happen at any point from turn 5 at which point I've played out my hand and nowhere to dump it. I've tried to add some land mana sinks like Arch of Orazca, Kessig Wolf Run, Sea Gate Wreckage, and Labyrinth of Skophos but also lands that let me sink mana to up my creature count if I'm short for Galia's trigger; cards like Urza's Factory, Crawling Barrens, Dread Statuary and Kher Keep; however, the deck could still benefit from more mana sinks. I recommend adding more cards like Seal of Primordium and Font of Fertility which are cheap enchantments that sacrifice themselves for their effect on a later turn thus avoiding being discarded.
