Therraway of the Red Moon

When Therraway enters the battlefield, create
Fluffy, a legendary 4/4 green Elemental
enchantment creature token. It has
"Other creatures you control gain +0/+2."
At the beginning of combat on your turn, you
may reveal a creature card from your hand. If you
do, Therraway becomes a copy of that creature
until your next turn and gains haste.
