Xurkitree: Favourite Ultrabeast by far, as much as I love the concept I find the rest of them as appealing
Double Strike, Vigilance, Reach, Haste Can't be Countered When Link is one the battlefield, the controlling player may add one artifact to their hand during their beginning phase
Prevented attacks until Mikaeus, the Lunarch activations spoiled his triggered ability, at which point he could still block one a turn but couldn't kill anything anymore
Not only do you get a sizable 2/2 for two mana, but you also get one of the best abilities put on a Rebel this side of the actual search mechanic
Rona lets you easily dump your targets, and Inti, another staple in the deck, helps too
if you are in red, you need to choose between Alpine Moon (the best Tron and Valakut hate), Damping Sphere (good Tron and Storm hate), and Blood Moon (reasonable Tron hate with free wins against other decks)
