Mono Primal Thunderstrike Dragons

Update 2 Feb 2 2019: Just 7-0'd after making Master Gauntlet, so it still has legs.

Update: This deck has a tougher time making Masters in Gauntlet. The power level of the AI decks has increased incredibly since this deck was first built.

Can't remember where I found the original list but I've been updating and tweaking this one for a while. The only mythic comes with the campaign, as far as I know.

Never keep a single power hand. Mulligan to two and a Dusk Raider, Favor, Second Sight or 3 power and a Wisdom. Use Second Sight to hide cards from hand disruption and especially use it to tuck and re-draw Thunderstrikes.

Gameplay is pretty straight forward. Set up your creatures and keep swinging, drawing cards and killing/disabling their stuff. Easily 7-0s Gauntlets and is decently competitive enough for casual, maybe competitive with tuning.
