Confirm, and I am guilty of having owned, and currently owning, functional decks that basically just boil down to mountains and lightning bolts. The “new” (decades old) rules forced me to diversify a bit, but Fallen Empires brought us the gift of the Goblin Grenade, so it’s all gravy for me. Four goblins and four Goblin Grenades is a win, even if you don’t attack with any of the goblins. You can spice things up in the interim with Lightning Bolts if you like.
