Having been a Test regular since his debut in 2022, Rio Dyer was overlooked by Warren Gatland for last year’s Six Nations.
The Dragons wing was recalled by Tandy for the autumn series, featuring against South Africa, and has been in fine form since.
His double against Newcastle Red Bulls took his record to four tries in five games as well as providing assists.
The 26-year-old has his confidence back and is finishing impressively, beating defenders, running strong lines and hunting work.
If Tandy follows Bristol’s lead by moving Louis Rees-Zammit to full-back, it could open space for the 24-cap wing.
“Rio’s got that X-factor and when he is confident, he means business,” said Dragons captain Angus O’Brien.
“That’s what we need – beating people in one v ones and lighting things up.”
Full-back O’Brien is in similarly fine form but might have missed the international boat at 31.
However, Dragons also have a pair of promising prospects in flanker Ryan Woodman and scrum-half Che Hope.
Hooker Brodie Coghlan became an international in the autumn and, after returning from a hand injury, is fighting to be Dewi Lake’s back-up along with Liam Belcher, Ryan Elias and Evan Lloyd.
