If you cast one, you won't have to pay an additional the first time you cast the other
As an added benefit, each time you cast your commander again, youll grow your graveyard even further and get an even bigger threat
A control deck focused on casting a high volume of instant and sorcery spells would benefit from including Tempest Trapper in their deck, as it provides additional mana for spell-casting and a potential card advantage engine with its ability to exile and play cards from the library

BPhillipYork: Great if there is a creature you want to get back to your hand for additional ETB triggers or maybe a hatebear you want to remove so you can do stuff on your turn, stuff like that
Dont be discouraged by this though
