How big CAN Mistform Ultimus get?

So the other day I was wondering "How big and nasty could Mistform Ultimus get in a tribal setup?" because of the above wallpaper. I mean, Mistform Ultimus is one of EVERY creature type. So what would happen if it was in a deck built for its creature types?

First some rules. The bonuses must come from a creature or enchantment or artifact that reads “all ____ (creatures) have X”, so no instants or sorceries. No -X/-X, even if the spell gives a bonus to other creatures. Must say “all” not “target creature.”

Also, I’m not going to include those that need another card to buff up the creature or those of exponential growth in the initial count; that will be later. I’m just not gonna do enchantments or non-creature artifacts at this time. There are too many and are too complicated, but I might add them later.

If all “lords” are in play:
Assquatch: +1.5/+1.5
Elvish Champion: +1/+1 Forestwalk
Goblin King: +1/+1 Mountainwalk
Kobold Overlord: First Strike
Lord of Atlantis: +1/+1 Islandwalk
Lord of the Undead: +1/+1
Lovisa Coldeyes: +2/+2 Haste
Zombie Master: B: Regenerate this permanent
Swampwalk

So already this sucker is an astounding +6.5/+6.5, can’t be blocked by Green, Red, Blue, or Black creatures, has first strike and haste, and regenerates. Yikes. What else we got?

Ok, what about other tribal leaders?
Aven Brigadier +2/+2 (both a bird and a soldier!)
Cabal Slaver Whenever MU deals combat damage to a player, that player discards a card
Daru Warcheif +1/+2 Costs 1 less to play
Deranged Hermit +1/+1
Dragonspeaker Shaman Costs 2 less to play.
Faerie Noble +1/+0
Field Marshall +1/+1 First Strike
Goblin Warcheif Costs 1 less to play. Haste
Lumbering Satyr Forestwalk
Kobold Drill-Sergeant +0/+1 Trample
Kobold Taskmaster +1/+0
Krosan Warcheif Costs 1 less to play.
Mistform Warcheif Costs 1 less to play.
Soraya the Falconer +1/+1
Undead Warcheif +2/+1 Costs 1 less to play.

Likes Your Creatures:
Oathsworn Giant +0/+2 Vigilance
Veteran Armorer +0/+1

So that equals a Mistform Ultimus cast for with Forest, Island, Mountain, and Swampwalk, First Strike, Haste, Trample, Vigilance and Whenever MU deals combat damage to a player, that player discards a card. Its final stats are 19.5/21.5!

That is stillnot including everything on the Sliver Legion Wallpaper! If I added those numbers the MU becomes 109.5/111.5 and could still attack if you go off of what the card originally said, defender or no.

Yikes! Add in Hivestone or Coat of Arms to that equation and my head starts to hurt. But those are activities for another day.
