Add Command Tower at least. It's a free mana of any color you want.
here's five cards that would ruin your game for you, or at least make it very annoying...
i would recommend rhystic study, grand arbiter the iv'th, wheel of sun and moon. Since prime time is banned now in Ontario, Kukusho has been unbanned, if i were you i would be looking to use the cloning, mimicking, shapeshifting blue white black red ability with Kikki-Jikki, the Mirror Breaker, / pestermite - deceiver exarct combo as back win/con. You have dauntless esscort but no way of anhilating the board, Novablast Wurm is nice for this, toss in some indestructables and you're set.
I find when I play black white green as a primary EDH, i'm usually relying on chance and tutor, or chance of tutor, through hope of deck/draw manipulation with artifact/enchantment/tutor ability. Instead it's better to let taxing blue enchantments do the drawing for you. Rhystic study early game to mid - to late game is a draw engine/kill target for you and your opponents, eventually yes, if they've survived to later game they can pay the tax, but by then its already done it's job and is now redundant.
Also.... rhystic study costs .50 cents. phantasmal image is good for this deck too, as would body double be, a lot ends up in the grave. Eye of Ugin + Duplicant + Vedalkin aethermage equals tutor for removal + every upkeep you can morph VA with trigger ability, then flip to copy creature in play ie: duplicant and rfg another threat, or fixer creature.
anywho this is long enough, ttyl.
A card that really needs to be in a progenitus deck is True Conviction (creatures you control have double-strike and lifelink). This makes progenitus a possible 1st attack win through commander damage
