Gatherer text issue for Abuelo, Ancestral Echo
It appears that the Rulings for Abuelo Ancestral Echo contain rulings that are for Abuelo’s Awakening.
Due to both cards having a flicker effect it is not obvious that it is a mistake.
The mistake can be confirmed from the source of the rulings: https://magic.wizards.com/en/news/feature/the-lost-caverns-of-ixalan-release-notes

I’ve posted it as critical, because if an opponent checks the gatherer text for official rulings, the mistake will put me at a disadvantage.
