If the hand you have is not very good and you think a random six cards from your entire deck would be better, mulliganing is the right move
It's also one of the first pinger options we see in Black, making it even better
It pairs especially well with token generators or cheap artifact spam
Willbender Willbender was first released in Invasion as a card that could effectively be hidden for its morph cost and act as a way to protect you or your other permanents
Mosswood Dreadknight For a surprisingly low cost, Mosswood Dreadknight is an easily recyclable draw card, stacked on top of a creature with great early-game combat potential
The enchantment side of the card is where we can get out advantages for card selection, and the fact that it is a may trigger also means if you cast a Star of Extinction with a Toralf God of Fury out, you dont have to exile your whole deck
