Why are there only 4 card draw spells in the entire deck
Most of the ramp cards generate one additional mana here, but there's a few Elfball payoff cards that generate insane ramp once the deck starts doing its thing, like Marwyn, the Nurturer, Elvish Archdruid, and Wirewood Channeler, which can ramp out some huge turns
For example, low mana value cards have low opportunity cost, and they tend to make positive tempo exchanges versus higher-MV ones, making those expensive cards less playable
Thada Adel, Acquisitor, is a fairly scarce card which has only ever been printed in the MTG set Worldwake in 2010
Hearthhull, the Worldseed Hearthhull, the Worldseed looks incredible to me
