The 25-year-old put pen-to-paper on a two-year deal with The Lions ahead of the 2016/17 campaign.
Wylde began his career with Scottish giants Rangers, making 47 appearances between 2008 and 2012 before a move to Bolton. His time at the Macron Stadium was frustrating, though, and he moved back north of the border - with a loan spell at Bury in between - to link up with Aberdeen.
The winger spent just half a season there before moving to St Mirren, where he began to display his clear potential, but after 18 months he decided to join Plymouth. In 2015/16 Wylde made 50 appearances for The Pilgrims, including against Millwall in the EFL Trophy, and scored seven goals - form which attracted the attention of Lions boss Neil Harris.
