This is especially true because of the Modern Horizons 3 Commander (M3C) precons

In the past with just Kuldotha Rebirth it usually wasnt worthwhile since your odds of drawing a Kuldotha Rebirth wasnt especially high and cards like Ornithopter and Memnite are pretty bad if they aren't turning into three 1/1 Goblin tokens, but now the odds are in favor of having one in hand every game

Oh, and its based on the intellectual properties of The Walt Disney Company

They also cant be countered by counterspells that say counter target spell. But some counterspells are capable of countering them, like Voidslime or Disallow since they specifically name activated abilities as something they can counter

If cards qualify on at least one of those categories, they are probably at least decent against Abzan
