Just lost 10 in a row with a CCYB variant, woo! 1/10,000 chance, top that! I even had Dream Catcher go 17 turns without drawing a Butterfly Effect, but I drew only one tower that entire time (12 turns in), and Dream Catcher drew that Butterfly Effect, two Black Holes, and a Quicksand before I got a second tower. Top that for perverse luck!
