So if youre able to wither them to death, you draw a card
However, there are a few other cards that deserve to be highlighted
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
And don't sleep on Mind Funeral either which can often dig so deeply that you can slip past Glimpse in power
