If they die, get exiled or anything else that removes them from the board, you can instead put them back in the Command Zone, but you have to pay two more mana to cast them - and that cost goes up every time
Another advantage this card has is that you can actually create copies that keep bringing spells back without having to sacrifice any of them to the legend rule since its not a legendary
As a 2/1 first strike creature for two mana, it's not the worst in combat, but it's ability is what really makes the card
Humility (T1, S, Block) Because of rules issues, this card should never have seen print
If you win all the flips, draw two cards for each flip
Draw decks are some of my favorite types in Commander, with Kwain, Itinerant Meddler easily being my favorite deck to play
