Thats about 15% of all Strixhaven cards linked to this mechanic, and you think none of them are going to come close to Standard play
But just like Pokmon and Magic: The Gathering, some Lorcana cards are worth significantly more than others, especially those tied to early releases, exclusive foils, or competitive play value
Making a 3/3 every turn is alright, but Garruk, Primal Hunter isnt really a playable card
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
You have plenty of time
