Elemental Hydra

When Elemental Hydra enters the battlefield, if you used at least {w}{u}{b}{r}{g} for its mana cost, put 6 +1/+1 counters on it.
If you also used {c} to pay for its mana cost, it also has trample and hexproof.
Damage done by Elemental Hydra cannot be prevented with any protection against colors.
