Finally, we have Setzer, Wandering Gambler
Requiting Hex Requiting Hex excels as a cheap and efficient piece of interaction
Its a powerful finisher any of the top token commanders would gladly include in their decks
It can be used to protect your board and life total while giving another opponent an extra turn, potentially making them a target for the next turn
You can then send them that card without spending any resources or using up a tick of regenerating energy
This way is to run cheap one and two mana cantrips that will target Blanka, trigger the ability to shoot your foes, give him a pump, and then it replaces itself and then you can do it again and again with the replaced card drawing you more gas, and then you have a big fat creature for the turn and damaged players
