Masters of Illusion / 8:00pm (50) Magic prevails for another summer as this showcase for prestidigitators starts its fourth season, with the amiable Dean Cain continuing as the series’ host. The first new installment — “Crazy, Crazy Cards and Stilly Silhouettes” — is likely to have its deck stacked, quite literally. Nathan Burton, Jibrizy, Joshua Jay, Farrell Dillon, Billy Kidd, Bill Cook and Xavier Mortimer are the guest illusionists featured. Another new episode follows.
Killjoys / 8:00pm (Syfy) Still reeling from the devastating losses they suffered last season, Dutch, Johnny and D’avin (Hannah JohnKamen, Aaron Ashmore, Luke Macfarlane) go on the offensive in the Season 2 premiere “Boondoggle.” With the help of an obnoxious black market dealer, Dutch and D’avin search for a weapon that will draw out the Hullen. Meanwhile, Johnny receives an SOS from Clara (Stephanie Leonidas) that leads him into the underground world of Hackmods.
The Great British Baking Show / 9:00pm (22) 1:00am (22) 4:00am (22) 9:00pm (26.4) Whether things go better with batter is up to the cooks to prove in a new episode revolving around that ingredient, which first comes into play in a round that requires it to remain uniform across the entire batch of one recipe. Then, it figures into a technical challenge also involving a sweet filling and icing.
Diners, Drive-Ins and Dives / 9:00pm (Food Net) 12:00am (Food Net) A new episode called “Island and Desert” finds host Guy Fieri starting out in the latter — specifically, Palm Desert, Calif., where a cafe dishes out such tasty fare as a succulent rib melt and breakfast tarts. Later, in Maui, Hawaii, a funky gluten-free spot makes full-flavored pizza, plus fish and chips. Finally, in Virginia Beach, Va., an offbeat Caribbean eatery serves up jerk pork and mama’s beef stew.
