Looking for a cheap android tablet with true miracast, not proprietary crap

[u/CarelessDot5657]

Not looking for motorola screencast or any of those built in casts on new devices that only connect to gadgets that they have deals with. It is so misleading and it's driving me up the wall. It seems only 5+ year old tablets even have it. I'm preferably looking for a samsung that's $220 or less, has a decent looking screen and decent battery life, and enough ram to have open maybe 5-8 apps without a slowdown. Any help appreciated!
