One of my favourite cards to play with in Constructed (just like
Fact or Fiction) because it is so skill-testing, but how good is this card in Riptide Cube?
I think that it could generally be too good (reanimator piles with big guys and
Unburial Rites, for example, or just searching for 4 really strong cards and getting 2 of them for 4 mana at instant speed - both scenarios sound pretty damn good to me) especially if I think about cutting FoF for being too good. You people already suggested
Epiphany at the Drownyard and
Fortune's Favor to me, which play very nicely in several decks, and I also added
Pore Over the Pages and
Moonlight Bargain as
very interesting options. Other draw effects usually are cycling, cantrips, looting, look-at-x-cards-on-top-of-your-library-and-pick(sometimes a certain type of)-a-card, and remove-from-the-top-of-your-library-to-play-exiled-card(s)-until-eot-or-next-turn (red). I'm pretty happy with that, as raw card draw is very strong but also boring, while the aforementioned kinds of card draw are all better in certain types of decks (cycling.dec, reanimator, selfmill, permanent/spell heavy and aggressive decks), so it's not always an easy pick in draft.
I read some old posts of Grillo and RavebornMuse that mentioned something about blue draw being too good and followed that thought, and after what we got in 2019 (which was A LOT) I think we reached critical mass to have card draw distributed among all colours to a certain degree, each colour being the best at something else or tied for the best for certain types of decks (red and white for aggressive decks, for example).
