There is a rule, which says "Your opponent may draw up to 2 cards if you don't have any Basic Pokemon in your starting hand." The way this works is, it has 59 Energy and 1 Mewtwo (Base), and what happens is your opponent draws tons of cards until you get that Mewtwo
Its expensive at $110, but worth it
It's everything you need to begin your collection
Think hard and combo the ninjas well, like Donatello, the Brains partnered with Splinter, the Mentor to create a ton of Mutagen tokens
Thats a lot to take in, but basically means youre going to likely be playing this on turn two and instantly drawing two cards
There are also some other utility lands that make it easier to cast creatures ahead of schedule, like Castle Garenbrig
