Might I suggest myrscoth golem or some other affinity? or more mox opals? also there tolarian acadamy which gives 1 blue mana for EACH artifact in play. it's a legendary land and very very meta for a very very good reason

Honest? chromatic lantern and or more farseek.

soggy, rakdos return is not late game. It's not fireball. You cast it for 4-5 mana just to empty your oponents hand then draw it later and finish.

burning tree DOES play into all the things you mentioned EXCEPT searing spear. You play burning tree into burning tree into burning tree if you can and there is NOTHING wrong in an aggro deck with making that play turn 3.

start by putting mindsparker and skullcrack in your sideboard. they don't belong in your deck. also add burning tree emisary over stormkirk noble, remove slaughter games and toil and troubble and one or two reakdos return

Glacial ray over skullcrack if you're running lava spike.

what i'm unsure about in this list is the disciple though. 3 ogres i think and if you really want to go a little greedy you can do a blood crypt and a kessing wolf run.

here's a suggestion to how i'd have made it, just charted up real quick

well i don't think you'll draw enough lands. i'd do 4 blood artists or some ramp. Gatevine creeper or farseek are good alternatives. your lategame can be Ogre slumlord, which i'd also have more of. If you need a little more lifegain or card draw then disciple of bolas with rancor. just throw it on a token or a rat to boost power, play disciple of bolas and replay next turn. Also only 2 lillianas and 2 paralell lives would be good. The strongest lategame card in that deck right now is actually Biomass Mutation. If you do farseek or lilliana then take out 2 swamps and 2 forrests and put in 4 overgrown toombs.

i like it when people actually respond to comments and try to make the decks P9:P

I'm not sure about grisle and aphendige but this is actually a golgari done really really well! i'm impressed

Lilliana of the Dark Realms perhaps?
but I like it. Not sure about your removals though, maybe add a Vampiric Nighthawk?

This looks really, really good. You may considder Arbor Elves instead of Llanowar Elves though.

It is indeed. I'd tweak it a little more and also add 1 Niv Mizzet, Dracogenius to main and toss something to have 4 of think twice

Druidic Satchel, Birds of Paradice and Llanowar elves must go to make it Standard. I know because I built it myself.

I am seldom impressed but this... this I can LOVE

This is really good but please try to update it to 60 cards, I'd love to see it. Thumbs up mate

May I reccomend "breaking" the 20 dollar mark with 1 vault of the ArchAngel? Exhalted + DeathTouch + LifeLink. Also I think Nefarox isn't really that good a creature but the knights get protection from removals, O-ring and Murder respectivly. 4 of each is how I'd have done it.
You're right though. It mulligans retardedly well.
Food for Thought.

If you're going to make a deck like this you really, really need Myrscoth Golem

Add silence for imprinting.

Make something leagal... in any format
