There are so many one-mana spells (or two-mana spells) that do this effect, plus let you have more agency over future turns, that casting either of these two spells is essentially throwing away a card
This can be used to ramp or enable combos that require sacrificing goblins for various effects, like Squee, the Immortals self-reanimation
Cultivator Colossus also works particularly well with landfall effects like on Tatyova, Benthic Druid and Aesi, Tyrant of Gyre Strait that let you draw a card when a land comes into play
His Hariyama succeeded in doing so, however
It's rarely a dead card because it can also target your own creatures, which means it can be used in a pinch to buy back a creature with a powerful enters-the-battlefield ability such as Druid of Purification or Uro, Titan of Nature's Wrath while untapping 2 of your lands
