Enchant land
When Security Blockade enters, create a 2/2 white Knight creature token with vigilance.
Enchanted land has “: Prevent the next 1 damage that would be dealt to you this turn.”
You must target a land to cast Security Blockade. If that land is an illegal target when Security Blockade tries to resolve, it won't resolve and won't enter. You won't get the Knight token.
Random a card of Magic: The Gathering (MTG), but you can also roll the D20 dice, random a Planeswalker, have fun with the random rules and more.
