Navalgazer Dragon teased in Vanguard anime

The fifth episode of the 2018 Cardfight!! Vanguard anime, "Let's Go to Card Capital!" teased several upcoming Aqua Force cards from V-Trial Deck 03: Sōryū Leon in its next episode preview. Among the cards shown are the grade 1 Tear Knight Theo, grade 2 Marine General of the Restless Tides Algos, and the grade 3 Navalgazer Dragon, all cards that debuted in the original Aqua Force Trial Deck six years ago.

Leon himself was briefly shown on television at the end of the episode, getting ready to participate in the Asia Circuit tournament. The title of the next episode, Image 6, is "Declaration of War!! Shop Competition." (In the sense of two shops pitted against one another, likely Card Capital and Voyage.)

The legible text at left reads "Born August 1st, male, blood type B, Aqua Force user. [...] Despite still being a middle schooler, he has participated in various large tournaments. [...]"

Tear Knight Theo and Battle Siren Dorothea.
