The Wizards Play Network has deck checklists for each set, which appear to be intended for use in limited events, but you could print them out and use them however you want
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
Niv-Mizzet, Parun can simply run Niv-Mizzet, Dracogenius and Niv-Mizzet, the Firemind for added redundancy
Bitterblossom provides exactly that, ensuring that your deck is always running in the optimum conditions
