For decks with three or more colors, where you might only be able to afford a small number of MDFCs since you'll need most of your lands to either be basics (for ramping / tutoring purposes) or tap for multiple colors of mana, the best MDFCs are Bala Ged Recovery (seriously, if you have green mana in your deck, play this card), Valakut Awakening, Hagra Mauling, and Ondu Inversion, along with the mythic cycle, which is almost always good if you can afford another land that only taps for a single color of mana
If youd like to play, wed suggest buying a starter deck
Otherwise you're just prolonging the game and delaying the inevitable
Timetwister is another juicy choice
And even though there were some unfortunately overpowered card drawing spells in the early days that were soon restricted, banned, or too expensive for play (Ancestral Recall, Braingeyser, Library of Alexandria) we still leaned on the artifacts
