Good point.

Then your options with Trickery are:
A) Cascade creature (8-16 hits)
B) Creative Technique (4 hits)
C) Tibalt's Trickery (3 hits)

C -> Complete fizzle. Revealed Trickery has no legal targets. Pass the turn.
B -> Demonstrate and go off with good consistency due to extra branches (but opponent gets free spells)
A -> Cascade creature could hit either:
Creative Technique (4 hits) -> Demonstrate and win with high %
Throes/Trickery (6 hits) -> Possible fizzle if it hits another Trickery

So the fizzle rate is approx 3/(3+4+12) (hit Trickery right away) + 12/(3+4+12)*[6/(6+4)]*[2/(2+4+11)] (hit cascader into Throes/Trickery into Trickery fizzle) = 15.8% + 4.4% > 20%
There will also be increased fizzling from Creative Technique lines, but I have treated those as negligibly small if you always Demonstrate (though that increases risk of opponent disruption).

You could improve those odds by running 16 cascaders instead of 12, but then there's much less room for lands. 12 cascaders already means cutting 4 lands. With 40 lands + 4 creative technique + 8 trickery/Throes, there's only room for 8 cascaders. With 8 cascaders and 40 lands that fizzle rate becomes: 3/(3+4+8) + 8/(3+4+8)*[6/(6+4)*[2/(2+4+7)] = 20% + 4.9% ~= 25%

You could also run fewer copies of Throes/Trickery and more cascade creatures, but then that speed line becomes less available.

Overall the Throes/Trickery tech introduces more variance, more fizzling, and more losses to a single counterspell. For that tradeoff it adds +1 turn speed. The question is how often is that speed worth it vs how much does the consistency loss hurt more? It deserves testing. But that is a high rate of error added.

A possible list to test for the faster line:
//Creatures: 12
4 Boarding Party
4 Aurora Phoenix
4 Maelstrom Wanderer

//Spells: 12
4 Tibalt's Trickery
4 Throes of Chaos
4 Creative Technique

//Lands: 36
4 Sandstone Needle
4 Dwarven Ruins
4 Sulfur Vent
4 Hickory Woodlot
4 Saprazzan Skerry
4 Ancient Tomb
4 Crystal Vein
4 City of Traitors
4 Gemstone Caverns

//Sideboard: 15
4 Pyrokinesis
4 Maddening Hex
2 Otawara, Soaring City
2 Karakas
2 Boseiju Who Endures
1 Emrakul, the Aeons Torn


You could also try to decrease the fizzle rate by running fewer Tibalt's Trickery and more multicascaders. Ex:
-2 Trickery, +2 Apex Devastator
Fizzle rate drops to: 1/(1+4+14) (hit other Trickery) + 0 (cascade creature cannot result in Trickery -> Trickery) > 5%
But there will be more lines where Creative Technique or Cascade reveals Throes and there are 0 Trickery left in library (that branch fizzles).
