Advanced search suggestion
In the advanced search, you can add text that would be in a cards rules. It has the options Not, Is, and Or. There should be an option Includes. This would allow people to search for things like enter the battlefield effects without having to put in exact names of creatures and all the details.
In line with this, having some way to search for cards that self-reference would be quite a boon.
Whether it’s copying (Myr Propagator, Nacatl War-Pride), restrictions (Master of Cruelties), or another scenario, allowing users to search for [this creature] would allow searching for similar formats without breaking up the template.
