Magmar is one of the more difficult factions to get 12 wins in Gauntlet with.
Below is a video showing a draft + full run to give you an idea of the kinds of cards and synergies you need to pick up in order to reach 12.
Six games out of the 12 were won because of Thumping Wave. A lot of folks are asking to nerf this card in constructed - but if it weren’t for the presence this card, Magmar would be even worse in Gauntlet.
There are quick-links at the beginning of the video (if you view on PC) so you can jump around to watch the parts you want.
Thanks for watching!
