A good amount of times, your card draw will be an ability of a creature, enchantment, artifact, land, etc
Please note: Due to the overwhelming number of not-factory-cut (NFC) Square Cut cards from the Wizards of the Coast (WotC) era, CGC Cards will not grade any Square Cut examples without a proven provenance back to a WotC employee
Well save the explanation of each different rarity and how to identify them for another time, but for the most part, the most desirable cards in collectors eyes are usually the rarest
The only exception to this rule is Machamp released in the 3rd print run of the base set, also called the Unlimited run
I could see a version of this deck running MDFCs but you'd need to be very clear that they don't trigger Riku, and it might be safer just to leave them out
