Over time, the cream will rise to the top and cuts will be made, but for now I like dabbling in a few of them and seeing which are best through testing
In the case of equipping one mana artifact equipment and redeeming mutagen tokens, those would then be free
Obviously, you dont really want to give up a real creature for the effect all the time, otherwise it is a roundabout way of rummaging, but recurring removal spells is especially potent, and giving up a creature for that is often going to be worth it, especially if you sacrifice a card that brings you some value when it dies
Thats a strong and compelling ability for a card with also powerful stats
Admittedly, tapping one creature in each of the first two chapters is considerably less good in Commander
