Magic the Gathering Crab Cannon Deck

Crab Cannon
This is a deck that I play with. It works pretty well. It has some counter in it.

Creatures:
1x Wall of Frost (Defender. Whenever Wall of Frost blocks a creature, that creature doesn't untap during its controller's next untap step)
1x Archivist (tap: draw a card)
4x Horseshoe Crab (1 blue mana: untap Horseshoe Crab)
3x Plaxmanta (You may play Plaxmanta at any time you could play an instant. When Plaxmanta comes into play, creatures you control can't be the targets of spells or abilities this turn. When Plaxmanta comes into play, sacrifice it unless 1 green mana was spent to play it.) note: this creature is to be used as an instant, because this deck does not have any forest lands in it.
1x Phantom Warrior (Phantom Warrior is unblockable.)
2x Brine Seer (2 colorless 1 blue mana and tap: Reveal any number of blue cards in your hand. Counter target spell unless its controller pays 1 colorless mana for each card revealed this way.)
2x Thieving Magpie (Flying. Whenever Thieving Magpie deals damage to one of your opponents, you draw a card.)
1x Hedron Crab (Landfall - Whenever a land enters the battlefield under your control, target player puts the top three cards of his or her library into his or her graveyard.)

4x Cancel (Counter target spell)
4x High Tide (Until end of turn, all islands produce and additional island when tapped for mana)
2x Daze (You may return an island you control to its owner's hand rather than pay Daze's mana cost. Counter target spell unless its control pays 1 colorless mana)
1x Negate (Counter target noncreature spell)
1x Sapphire Charm (Choose one - Target player draws a card at the beginning of the next turn's upkeep; or target creature an opponent controls phases out; or target creature gains flying until end of turn.)

3x Divination (Draw two cards)

Enchantment:
4x Hermetic Study (Enchant creature. Enchanted creature gains " tap: This creature deals 1 damage to target creature or player."
4x Ocular Halo (Enchant creature. Enchanted creature has"tap: Draw a card." Pay 1 white mana: Enchanted creature gains vigilance until end of turn0

Lands:
20x Islands

The main thing to do with this deck, and the reason it is called Crab Cannon, is to get a Horseshoe Crab into play and enchant the creature with a Hermetic Study. With the Horseshoe Crab you are able to pay 1 blue mana to untap it and the Hermetic Study deals 1 damage to target creature or player when tapped. So if you have a good amount of blue mana on the field you can tap Horseshoe Crab, that is enchanted with Hermetic Study, to deal 1 damage to target creature or player. Then you pay 1 blue mana to untap Horseshoe Crab and the process starts all over again, like a cannon. You can also play a High Tide, which cause your blue mana to produse an extra blue mana when tapped for mana, before the process happens. This allows you to do double the damage.
