(See rule 510, Combat Damage Step.) 702.7b If at least one attacking or blocking creature has first strike or double strike (see rule 702.4) as the combat damage step begins, the only creatures that assign combat damage in that step are those with first strike or double strike
Reading these cards could never explain these cards, and for my money, thats a design step too far
Not a bad package, all things considered
Abilities and Skills: Psychic-Type Moves: Mewtwo has a vast array of powerful psychic moves, including Psychic, Psystrike, and Teleport
Without Legends , we wouldnt have the Legendary supertype (or the Commander format) or multicolored cards, and Magics lore wouldnt be nearly as well-integrated into the game
