I get that Mercenaries and Rebels were big creature types for Mercadian Masques block, but it feels really jarring to put a creature into a tribal deck that doesnt fit the tribe even if it works well and has clear synergy with your game plan
One deck comes with Slifer the Sky Dragon, while the other comes with Obelisk the Tormenter, letting you pick which side you want to play as
It makes all your spells cheaper with affinity for artifacts, and it comes with double strike and vigilance to keep the pressure up
When that creature dies this turn, return it to the battlefield tapped under its owners control
Notable cards from the set include Emboar-EX, Beartic-EX, Kyurem-EX, Zekrom, Eelektrik, Zapdos and Articuno
