I think the extra steps you have to go through and limited types of cards you can steal makes it a slightly less contentious choice if you want to build a deck in that direction
Creating an additional list is something to be very careful about
This feature saves a massive amount of time and makes the process of valuing your collection much more efficient and enjoyable
It cant block, which is a minor downside compared to the long list of benefits it provides
Ideally you'd be putting this on something withy lifelink to keep the gains going, or even Qala, Ajani's Pridemate to increase the buff when it swings with other creatures
