The triggered ability of Rings of Brighthearth and the copy it creates both resolve before the ability that caused it to trigger
The more copies of a legend you have, the more likely it is that you'll run up against a situation where you can't actually play your cards because of the legend rule

Rally your troops, embrace the chaos, and lead your legend to victory
It deals X plus 1 damage instead if that target is a creature or planeswalker
