Vigilant is a really good card that sees very little play. Its too slow for red based aggro decks, too slow for more classic midrange archers, and slower warriors aren't really a thing (although maybe with the new card ramp warrior is a thing?). Its in some rage based archer decks though since it cycles itself, has breakthrough and high attack to combo w/ rage, and can get the cost reduct frm TGR.
Something like this:
https://www.legends-decks.com/deck/1...stream-8-23-17 (which also has ungolim). Unfortunately its fairly expensive but you get astrid and garnag for free from dark brotherhood, brynjolf from the pre-constructed deck, and a few copies of the epics from the story mode, pre-constructed decks, and leveling up.
Also not sure what level you are but you get a free vigilant giant at lvl 20 when your dude evolves/upgrades into one.
Ungolim used to be in every green deck ever because he was as 2/1, as 1/1 its harder to find a spot for him in non-lethal/rage lists.
Ps, guys feel free to add me, AvgSizedP_Nis, think I only have namath and sjud on friends list. Mainly playing daytime EST at work on and off but sometimes later on. Think I'm gonna make a run for legend, currently 2 wins away from rank 1.
