Another reason to accept evolution.....

[Angrboda]

Other than the fact that we see the small mutations and no giant leaps in "the design", you mean?  Not for nothing...but if you want to propose giant leaps..you;re going to need an entirely new mechanism..because that;s not how biology works.

At that point, what relevance does biology or biological data have to this hypothetical magic trick?

Fossil evidence and design in some parts of biology of creatures, I believe clearly shows, both happen. Small mutations and big leaps.  Small mutations cannot lead to all design, even if they traversed linearly because of irreducible complexity of some designs in biology.

Gould and Eldredge argued that punctuated equilibrium is in contrast to Darwin's version of evolution. They stated, "To Darwin, therefore, speciation entailed the same expectation as phyletic evolution: a long and insensibly graded chain of intermediate forms." Some scholars have argued that Darwin was not a phyletic gradualist.[3]

It is commonly believed that punctuated equilibrium is the opposite of gradualism. However, this is due to a misunderstanding of the definition of gradualism. Although PE is in contrast to phyletic gradualism, that evolution happens slowly and by transformation of species, it is nonetheless a form of gradualism in the sense that it predicts evolution by minor genetic changes between generations.

Some misconceptions of punctuated equilibrium are due to misunderstanding its tenets. PE's tenet of long periods of stasis in a fossil species does not mean that it does not change at all but rather that change varies around a mean and does not accumulate. Likewise PE's tenet that instances of change will appear instantaneous implies that such change will be rapid relative to geological terms but will in reality take many generations to occur.
