Temur, the identity of blue, green, and red, is a robust combination that has access to impressive card draw, mana ramp, and aggressive creatures
But Nibelheim Aflame is cheaper, you can cast it twice thanks to flashback, and the second time you cast it, you discard your hand and you draw four cards
It also makes 'black and red spell considered colorless damage', which is a rather specific way to prevent them from being countered by counterspells that cares about a specific colour
Enchantments have persistent magical effects that influence the game as long as theyre on the battlefield
Put target creature card from your graveyard on top of your library
EDIT : A friend pointed out that a sorcery and instant with landfall does exist, so the RNN actually wasnt the first one to experiment with that
