Buff them crabs and annihilate your opponent.

This is a pretty aggro deck. Hopefully it has enough removal to hold the fort until we get some +1/+1 counters going and a couple rounds of proliferation. [[Ichthyomorphosis]] and more.

Aesthetic Goals: Keep hard to the crab/fish/ocean theme as much as possible, keep to blue and green only. More blue that green.

Mulligan until you have at least one Forest. You'll need it.

It may seem like the manna curve is a bit shallow, but there's [[Clutch of Currents]] and [[Earthen Arms]] that can be cast for their Awaken cost of 5 and 7 respectively for some misfit 3/3 or 4/4 Land Elemental backup in addition to their regular effects.

Counters & Proliferate

The main keywords. We got 13 cards that add counters and 9 that proliferate. Try to save the proliferates until you get at least two tokens. Maximum value.

Draw

There's a bit of draw, 7 cards.

Weirdos

[[Clutch of Currents]] and [Earthen Arms]] both charge up a land to 3/3 and 4/4 respectively with tokens that can then be proliferated.

Debuff/Removal

There's plenty to keep yourself safe as you build up the +1/+1 or -1/-1 counters. Direct destruction, return to owner's hand, and tapping can keep your opponent busy.
