This is an interesting point of view, but imo there are better sideboard options :
Sphere of Resistance > Thalia/Thorn of Amethyst
Sphere is much more resiliant and tax everything, not just non-creature.
Pithing Needle > Phyrexian Revoker
Same reason, much more resiliant
These creatures and Taxes effects will always hurt our game plan (Punishing Fire, Life from the Loam, Explosive) while being sometime useless against others creatures and less powerful.
Smokestack is a real killer against lot of deck.
Just land it and let it doing its job.
My sideboard for reference :
4 Chalice
3 Sphere of Resistance
3 Smokestack
1 Crucible of Worlds
3 Abrupt Decay
1 Tormod's Crypt
