The highlights of this deck include Rumbleweed, a monstrous creature that comes loaded with an enter the battlefield Overrun effect, an Ancient Greenwarden, which has an incredible ability to copy your land-based triggers, and Embrace the Unknown, which can help turn your lands into Impulse-draws later in the game
The dice are rolled sequentially
Pack Points aren't the most efficient way to get cards, since it can take a while to accumulate and rarer cards require a hefty amount of Pack Points
I wouldn't build specifically around this just because there are easier ways to ramp, but if you're already going the cuisine route with your deck don't leave your Halflings at home
Of course, its possible to purchase goodies within Magic: The Gathering Arena
Notice when abilities fire and how they stack with each other
