I’ve made it my mission recently to look back at the Un’goro quests and see if I can make them somewhat viable - Jungle Giants is the first! I’m running a ramp Druid shell with Winged Guardians, Fizzy Elementals, and Scrapyard Colossi. It’s been great so far! I tend to destroy slower decks, as most can’t keep up with the value of several hadronoxes each turn, while aggro decks are a bit of a tossup.

1 Naturalize
1 Wrath
