I can be wrong, but I think your deck lack consistancy.
Playing a 5 colors commander isn't easy and it need a strong synergy between creatures.
BUT as far as I know, Allies were created in several extensions and not always in the same colors. I can remember an ally with more than 2 colors...
So, indeed, they have effect that is based on the amount of allies, but I don't think is a strong enough synergy.
I think you should go for a 2 colors deck. For exemple with
Akiri, Line-Slinger +
Bruse Tarl, Boorish Herder or
Munda, Ambush Leader (even if I think that one would be better on
simple creature).
Aside from them, you have a lot of allies that are great to play on those colors :
Munda's VanguardKazuul WarlordAngelic CaptainAngel of RenewalAlso, you have a lot of creature. You should only be around 30. The only deck I know that have so many creature is one I've done. A tribal one too, but based on sliver. It works well because each one bring a capacity that can help to solve a particular problem. They are less dependant on spell, enchants or equipements.
With 2 colors, you'll also be able to
shrink a little your manabase. For 2 colors, you could spare about 5 lands.
So you could have more that 20 spare slots. With those you should add :
Removals
Draw/Tutors
Artifacts (and mostly equipements if you use
Akiri, Line-Slinger)
Also, severals allies have capacities that :
need to be tapped => Find some cards that give
Vigilance so you can attack and use their capacities in the end of your opponent turn.
trigger when they come in play => Find some blink effect for even more triggering
Conjurer's Closet is interesting, but as it bring the creature back in the end of the turn, it isn't very useful with
Firemantle Mage for example, as it come back after combat phase. But it can be great with :
Hada Freeblade,
Kazandu Blademaster or better
Kazuul WarlordFor the others creatures that have effect when
entering battlefield you can use
Acrobatic Maneuver or
Astral Slide (with cycling lands for example)
I'm sorry for that very long response and for suggesting such radical changes but I really think that it will be hard to improve your deck if you keep five colors.
