If youre facing a board state where you cant afford to summon it, thats fine
Then the answer is yes, and this thing is going to be a beater
Being that ninja decks can be a bit mana hungry, that cost reduction does a lot of work for us
Once it actually hits the battlefield, the deck can snowball hard
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
With a few Dragons in play this card will be drawing you three or more cards a turn, or burning your opponent for six
