Pretty simple gruul Smashin' with a little simic bio-engineering mixed in.

Your elves look a little gnarly bro...

backup win is a nice face smash with clan defiance also keeps the board stable with some nice 2 for 1 and a few rare 3 for 1 . With some archdruids or some decent ramp can be lethal

Maybe wanna throw in some signal the clans for when Im stuck durdling with too much mana could fetch pretty much any winner or another biomancer.

Weak Vs. Control trying to come up with some sideboard ideas

Most every time I end up using simic charm for the giant growth to stunt aggro but I'm not sure if its worth it to drop it for plain growths.

Biggest problem is durdling on a fat stack of mana with nothing to do.

Sideboard: Pithing Needles: Planeswalkers, ability lands, others just good to have around especially on control.

Garruk's: good against boardwipes for control and add extra draw to try and outrace the matchup

Maybeboard:3x Strangleroot geists-> 3x Spire Tracers : Im pretty sold on this, the spire tracers seem nice in theory but under perform most times.4x Spell Rupture -> ???: I love this card as a standard mana leak and is especially good in a control/midrange matchup and will definitely be in the sideboard I would like to mainboard it but i am not sure whereRancor and Signal I am still not sure about how I would fit in right now but they seem to fit very well.
