Momentous Moray

{4}{u}{u} Monstrosity 5. (If this creature isn't monstrous, put 5 +1/+1 counters on it and it becomes monstrous.)
You may pay {e}{e}{e}{e}{e}{e}{e}{e} (8 Energy Counters) instead for the monstrosity cost.
While Momentous Moray is monstrous, it gains Reach and can block an additional two creatures each combat.
