Its a shiny holofoil promo
Well, when it enters the battlefield, it's like a mini Craterhoof, granting +3/+3 and trample to your other creatures until the end of turn
Mechanically, this isnt just another +1/+1 counter deck: It feels like something very new
Its easy to set up and, most importantly, it is consistent with the power to take down many of the toughest Pokemon in two hits
Pairing it with Zealous Conscript creates an infinitely large army of 3/3 creatures with haste, pairing it with Worldgorger Dragon gives you infinite mana and infinite enter-the-battlefield triggers, and pairing him with Combat Celebrant gives you infinite combat phases
As long as you craft a slower deck devoid of Game Changers, two-card combos, mass land denial, and extra turn spells, most Commanders are fair game
