Hydragon Chromus

When Hydragon Chromus enters the battlefield,
if it's not a token, create a token that's a copy of it
for each nongreen color of mana spent to cast it.
Those tokens' colors are identical to the colors of
mana spent to cast this spell. (For example, if
{w} was spent to cast it, the token becomes white.)
This creature has lifelink as long as it is white,
hexproof as long as it is blue, deathtouch as long
as it is black, haste as long as it is red, and
trample as long as it is green
