Almost every Ragavan, Nimble Pilferer deck plays the two-mana sorcery alongside it, as the more mana you can create, the better Iteration is as it is not being forced to take lands from it/having the mana to be able to cast any card you hit makes Iteration closer to a two-mana spell that draws two of the top three cards, which is utterly broken
Collectors often appreciate familiar Pokmon appearing early because it brings balance to the group of first cards
The trouble is, his effect, while a good troll, is not that powerful, quite annoying to keep track of, and easily telegraphed
