How my Phonics class plays “Go Fish”

My class uses Upper and Lower case alphabet cards to play Go Fish. This is how I fool kids into reinforcing their alphabet acquisition. BAM!

Julia: Justin (She always chooses Justin) do you have an “a” card? 
[Walks over and shows Justin the “a” card]
Justin: [Looks through his pile of cards] Go sit in your seat.
Julia goes back to her seat.
Justin: No.
