Time Stretch is often compared to Time Walk. Possibly, because what they do is the same. Time Walk might be cheaper than Time
Stretch but it will let you take two turns in a row! And when you are on a roll, mirari it for two more extra turns! Well with a cost anyway.
It might be too expensive and might be hard to cast during play, but when paired with powerful cards, victory is almost yours. Time Stretch is usually played with Wormfang Manta, Relearn, Peregrine Drake and Treachery.
Not everyone may be able to afford this card (it costs 10 mana), but it is definitely worth it, because once you played it well, it might earn you another two turns in the next round!
