Signal Jamming Station

Each player can't cast the card type of the last
card they cast on until the end of their next
turn.(if you played a creature, the next spell you
cast has to be a noncreature spell until the end of your
next turn, if you played an enchantment, the next spell
you cast has to be a nonenchantment spell until the end
of your next turn.)
We can't stop the invasion, but we can certainly
slow them down.
