Dont usualy throw my hat into the ring but this problem i just might consider it.

I am also making a kykar deck and its nice to see it from another perspective.
Mine is more focused around some spells with a x cost so i can sacrifice spirits for mana so i can cast large blue and red sun's zenith.

Something like [Moggcatcher] and the [Goblin Recruiter] to get some goblin tutors to fetch the goblin you want can also be usefull
this might just be a bit personal but one of my favorits a [Siege-Gang Commander].
Since you are making plenty of tokens [Impact Tremors] would also just wreck.

Thats true something like Shrieking Affliction and/or Skullcage could also do some good work here since you will be empty you'r opponent's hand quick. And they will be a bit more budget friendly.

If you go this heavy discard rout , something like "Waste Not" would be very nice in this style of deck.

True in that sence i like riskfactor better because you can target the person at the table with the lowest life total.
But i do like the way the decks looks

Cool deck but could run out of cards fast tho. Something like Risk Factor or Browbeat for some quasi draw\damage or a shrine of burning rage.
Got a sudden urge to build it..

A infinite mill of all is Painter's servant and Grindstone. With enough draw nd tutors there are hope to assemble them

Staff of Domination and Metalworker with 3 artifacts in hand is a fun one as well

You could swap Channel the Suns out for say somthing like Chromatic Lantern.
You got the infinite loop of mana in Pili-Pala and Grand Architect that could help you if you want to stay in scarecrow's and cast you'r expesive spells.

Looking at the cost of the deck is so low on mana you don't need 24 lands so maybe drop to 22 lands and cut the Changeling Berserker for another krenko wouldn't go 4 of them 3 seems fine. I would cut the bloodmark mentor as well.
I would maybe swap the Goblin Arsonist for a set of Legion Loyalist with the buffs you got could be powerfull.

If you are going to swap teeg out i had some good results with painter's servant he messed the game ut for a aldrazi playing friend since he couldent use his lands to cast colorless spells. Ad him as say white and the liege will buff him.

Looks fun Paradox Haze vould be fun in multiplayer

Maybe Overwhelming Stampede instead of overrun since there would be close to, or always a bigger creature then a 3/3 when you cast it

Mardu Ascendancy woulde be fun add. And then swing there is goblins and they are everywhere, one can never get enough of them.

Witches lets see you see if they float then you need some other thing that floats like... (werry small rocks) or a duck.
Then you way the witch and the duck if they are equal in weight you may drown the witch

hmm grave titan or helldozer would be fun in this deck. And since you are doing legacy you can down to 22 lands and ad 3 dark rituals.
two or three Cabal Coffers if budget is no problem

yeah it is i use them in my commander decks and if you pull them you got a huge advantage

Ah. Nevermind me then

Possible one or two memory jar's would have been fun in this deck. 7 new cards to use lots of draw and discard
