Goal: Cast any card with cmc N on curve with a probability of 89% + 1% * N.

Land Mana Symbols:

22 Lands

4 green only land sources
1 blue only land sources
2 red only land sources
0 colorless land sources

4 any color source
4 green + blue land sources
4 green + red land sources
3 blue + red land sources

= 16 green sources (+ 4 on turn 2 | + 2 on turn 3)
= 12 blue sources (+ 4 on turn 2 | + 2 on turn 3)
= 13 red sources (+ 4 on turn 2 | + 2 on turn 3)

= 20 green or blue sources (+ 4 on turn 2 | + 2 on turn 3)
= 21 green or red sources (+ 4 on turn 2 | + 2 on turn 3)
= 18 blue or red sources (+ 4 on turn 2 | + 2 on turn 3)

+ 4 Attune with Aether. They can be counted as + 1,0 * 4 mana sources of either color for cards with cmc 2 or higher. Though they act like a tap land.
+ 4 Servant of the Conduit (which are irrelevant on turns 1 & 2). They can be counted as + 0,5 * 4 mana sources of either color for cards with cmc 3 or higher. Though they act like a tap land.

Conclusion

We rely on Attune with Aether to sculpt our mana sources from turn 2 onward, though it basically acts like a tap land and can only fetch up to 1 blue and 2 red sources.
Not being able to cast Glorybringer for 3RR on turn 4 or 5 could be a disaster: Relying sorely on lands, there is a probability of 92,4% to cast it on turn 5. Attune with Aether & Servant of the Conduit raise that value to 99,9%.
Casting a turn 2 Negate or Essence Scatter will be possible in 90,1% of cases if you account for lands only. Attune with Aether raises this value to 97,0%.
