Gruuls on the beach partying and doing things thier mothers wouldn't approve of!  These Gruuls are wild and ready to crush all opposition.  Yes, even you, there in the corner.  Crushed.  Like a grape.  Don't worry.  The janitor has a squeegee.  You won't make that much of a mess.  This deck has a slow start but warms up into a lot of damage very quickly if left unchecked. 

Bonecrusher: shock for 2 big body for 3.

Destiny Spinner:  Ruin the counter game on your creatures and enchantments.  Decent lil 2/3 bod as well for 2.  Green in the cost.

Rhonas: Everyone just explodes in glee when he pops in.  Abuse it.  Repeat offender for the felony of causing people to rage quit.  Generates salt.  Has 2 green in cost.  Oh and he recurs.  Kill him?  Fine.  Deal with the kamehameha again.

Spellbreaker:  3 for a hasty 3/3 or a standard 4/4.  Eitherway, it gets haste and hexproof for it and you on your turn.  Noice.

The Beast of Questing:  Just a house. 2 green.

Renata:  lil janky?  maaaaaybe?  She makes other summons better and soaks up all that green devotion I've been mentioning into sometimes superb attack power.

Hydra:  comes in 2 attack modes:  ninja assassin and avalanch.  2 green.  Nearly always a happy draw.  This, bonecrusher, and return to nature make up the creature removal suite in the main deck.

The Goblin: a cheaper smaller non tramply version of spellbreaker.  But you'll often find yourself in chances to put out 2 of these in a turn as 4/4s or even 5/5s.

embercleave: + 1/1 and double strike.  Put on death touch or big trampling creature for best results.

return to nature:  so many enchantment and artifact builds, and if not those, then crap you need to get out of their graveyard.  Very meta.  Repeal is in the sideboard in case you need to bounce indestructables.

Rhythm of the wild:  tried so many times in the past with this that I never thought it would work, but dagnaggit, it works pretty well as a 3 of here to haste the slow things and buff the fast things.  Plus it's another layer of protection from counters to creatures.

Sideboard:

Sweaty ceratops: his foul odor doth offend dream trawler.  Include against mixes with white/blue

flame sweep: irritates cat oven decks and mono red.  Go ahead, nothing in our list dies to it.

repeal:  thassa, heliod, etc... the pain in the rear end stuff return can't deal with.

spyglass:  killing planeswalkers with Phosphoros' Intervention is an idea too, but more will just come.  I find this a bit more effective and the info from the hand scout is handy.

tibalt:  We don't like people gaining life.  they are supposed to be doing the opposite.

That's all, good luck out there! 

Added Note:  Next up, I'm going to try to put together something more low to the ground.  This has an average cmc of 3.22, really higher than that considering x cost creatures.  I wanna try to build a list running more around 2.
