Multiple ways to build Ulalek.
1) Flash double spell Eldrazi with CMC 2.88 Eldrazi
2) Cast Panharmonicon with CMC 5.77 Eldrazi
3) Cascade value with Zhulodok/Imoti with CMC 7 Eldrazi


Winding Canyons is reserve list
Anything with a "create spawn/scion" can go infinite with a critical mass.
Hmm, Annie Joins Up; Delney, Streetwise Lookout; Echoes of Eternity; and Roaming Throne allow a 2nd Ulalek trigger without paying for a 2nd spell. Cost A+2N. Result A*2^N. Value A^2*2^N. If A^2 is accurate, then desired A=5.77. If A^c is more accurate, then the number varies but is constant for a given c.
max{X^2 2^Y|12 = X + 2 Y}≈288.443 at (X, Y)≈(5.77078, 3.11461)
max{X^1.75 2^Y|12 = X + 2 Y}≈189.164 at (X, Y)≈(5.04943, 3.47528)
max{X^1.5 2^Y|12 = X + 2 Y}≈128.583 at (X, Y)≈(4.32809, 3.83596)
max{X^1.25 2^Y|12 = X + 2 Y}≈91.1392 at (X, Y)≈(3.60674, 4.19663)
max{X^1 2^Y|12 = X + 2 Y}≈67.9344 at (X, Y)≈(2.88539, 4.5573)

If I double spell (aka flash), then I cast A, put trigger on the stack (never plan to pay this one), cast B, put trigger on the stack
Stack: ATBT
Resolve trigger gaining the trigger again (only if both were Eldrazi)
After resolving the trigger N times I get A*2^N + B*2^N
Cost: 2A+2N aka (A+N=C/2=c)
Value: A*2^(N+1)
max{y^2 2^x|x + y = 5}≈36.0554 at (x, y)≈(2.11461, 2.88539)
At 10 mana, and even at higher mana, if I am generous and assume creature value scales quadratically, then it is optimal to use CMC 3 Eldrazi and just increase the number of triggers.
