The 7x7

If you have eaten a cheeseburger in the last 7
hours, "The 7x7" costs {7} less to cast.
If any creatures attack you while you control "The
7x7" remove them from combat and prevent all
combat damage that would be delt this turn. They become tapped and do not untap during their controller's next upkeep.
"It's just so good..."
