When Ygra, eater of all and Toph, the first metal bender are on the battlefield when you play Mythweaver Poq, the game sees mythweaver as artifact food and therefore a land, so it duplicates, but the legend rule doesn't allow two mythweavers so it makes me sacrifice one. HOWEVER, no matter which one I choose, the game just assumes that the copy is the one that remains on the battlefield, starting a new dupe trigger and the cycle happens infinitely until I run out of time. Please make it to where you actually are able to choose the original OR the copy in the future because I'm sure there at least a few circumstances that would benefit greatly from the ability to choose, such as this one.
