Really want some tips and pointers! And a way to utilize all dat tasety mana! I could justaswell go with a penta colored deck because pentacolor is awesome!

If you want to make your Myr bigger, since they start off small, go with a {Steel Overseer}, or, if you have the cards and ways to get combos started, use a {Xenograft} with the {Sliver Legion}. A bit unorthodox for a Myr deck, but it certainly helps them.
({Myr Battlesphere} for the win!)

Edit: if you do use the graft/legion combo, run a {Myr Tubine} as well.

{Myr Turbine}
{Myr Battlesphere}
{Master's Call}
{Shrine of Loyal Legions}
{Myr Resivoir}
{Myr Propegator}
If you want to go colored, try
{Tezzeret, Agent of Bolas}
{Devil's Play} (Myrs make infinite mana for burning)
{Alloy Myr}
