5 Color

[Arzair]

I am having trouble linking it, but maelstrom archangel is awesome in 5 color.  One of my favorites, I wish it was legendary.

{door to nothingness} and {rings of brighthearth}

Watch out for the willbender morphed trap on that one .   

P.s. - I am having trouble linking cards since the most recent update

Already in there

[Arzair]

Just saw that the archangel is already on your list... Again sorry for lack of links... Updated and hasn't worked since...or haven't figured it out lol

Serious suggestion:
Land fixing - all ten original duel lands would be the best... But not in everyone's price range
All ten shocklands
All ten check lands

Look up bloomtender - 2 drop that potentially taps for 1 of every color (5 total)

Elemental theme:
Your commander screams "build around me"
Fun recursion with evoke elementals for increasing options and versatility/flexibility

Lurking predators- perhaps cut the number of spells and increase the number of reusable creatures to maximize both potential plays
   Possibly get a creature that has etb effect for every spell cast by another player... Huge fun in multiplayer.

Warp world - if you don't like the present bard state, this can be a huge swing in the game, especially with etb effects and the possibility to overwhelm immediately with haste enablers... Fun ones like ( akroma's memorial)

A possible sac outlet - insurrection clear everyone's board but yours,

Homeward path - not mana fixing, but stops your big threats from being stolen, see also, bribery... They can try to bribery you, but you can just gain control of your creature

I will keep thinking of cards/ strategies, and post as I think of more. Hope this helps

 {Mundungu} - counter speller
{Acidic Slime}.- etb artifact/land/enchant destroyer
{City of Brass} - all mana
{Notion Thief} - extra draws
{Devout Witness} disenchant/kill artifact
{Legacy Weapon} - exile machine
{Wheel of Sun and Moon} - forever recycle cards
{Sylvan Primordial} etb mana ramp and game changer
{Swiftfoot Boots} - hexproof your .poo.!

I would suggest  {Cromat} over prog unless you have some good mana ramp.

Cromat is also pretty versatile, Progenitus is pretty epic also, but Cromat will be out faster; can protect you from flyers, and you can then elvish piper Progenitus so he could be out turn 4/5 depending on hand/ramp

{door to nothingness} and {rings of brighthearth}

{Channel the Suns} +  {Reverberate} +  {Door to Nothingness}

[Double-O-Scotch]

Enters tapped...

[Gorzo]

Enters tapped...

Adding an {Amulet of Vigor} would fix that problem.

[Double-O-Scotch]

Yes it would...lol

I've been putting the finishing touches on my 5 color EDH deck. I happened to have an Atogatog, a sliver queen and a Cromat/child of alara deck so I've been  thinking about combos for these decks.

{Isochron scepter}
Possibly want a copy artifact enchantment also since you have so many great tools for 2 mana that people sometimes only have one to use in EDH

{path to exile}
{swords to plowshare}
{pull from eternity}
{silence} (add the artifacts untapp during opponents phase for even more hate)
{redirect}
{reverberate}
{counter spell}

[Gorzo]

{Orim's Chant} is hilarious and cruel with the scepter, especially of you have {Unwinding Clock}.

{Angel's Grace} isn't bad either, not only for it's effect, but sometimes just for Split Second.

u should use all of the different versions of  {Golgari Rot Farm} instead of some of the basic land/ gates becuz it gives u both colors instead of picking which one u want from gates

[IntoFire]

{Gemhide Sliver} + a  {Door to Nothingness} is always fun.
