The Universe Traveler

The maximum The Universe Traveler cards a
deck may have is one.
You may reveal this card from your opening hand.
If you do, add {w}{u}{b}{r}{g} at the beginning of
your first main phase. Creatures you control gain
haste and become unblockable until end of turn.
When The Universe Traveler deals combat
damage to an opponent, shuffle it into your
library.
