Shell Shield

Cooldown 3 - Makoa
When Shell Shield enters the battlefield, and at
the beginning of your upkeep, put a shell counter
on this card. Creatures you control get +0/+1 for
each shell counter on Shell Shield.
{1}{g/u}{g/u}: Until end of turn, creatures you control
deal damage equal to their toughness instead of
their power.
I will weather this storm!
