Time Paradox

When Time Paradox enters the battlefield,
choose a colour.
Reveal the top three cards of your library.
If two or more of the cards are of the chosen
colour, take an extra turn after this one.
If one or fewer of the cards are of the chosen
colour, end the turn.
Put the cards at the bottom of your library in
any order when done.
You can only activate one "Time paradox"
per turn.
