Everyone's experience will be different based on where they're ranking, and I personally saw a lot of green and red/green decks running Silverback Elder immediately after Dominaria United was released
In a deck with the creatures to back the fight side, this offers lots of flexibility with your open mana
Both are great ways to draw even more cards, and you can certainly go hard on both mechanics if you want to
The Immortal Sun Like several other artifacts in this ranking, The Immortal Sun earns its place not just by its card-drawing effect (which, if taken in isolation, isnt that great for a 6-mana artifact) but by the whole package it provides
There were decks that could combo off turn one thanks to cards like Tolarian Academy allowing for insane mana production
