Spelling Bee

Whenever a player casts a spell, he or she puts it onto the battlefield face down while it is on the stack. Before it resolves, it's controller reads the name out loud. Then each player tries to spell out the name of that spell. Each player only gets 1 try. If any player spells the name of that spell right, counter that spell.
"T,A,R,M,U,G - Wait a minute. Is it TARMU or TARMO? How do you spell Tarmogoyf again?"
