Crab-related mechanic

I have been thinking of making a small custom set themed around giant crabs (Kindly don't question my reasons). However, I am struggling to come up with a properly themed mechanic. The only idea I have is Armour, which reads as

Armour N (This creature enters the battlefield with N armour counters on it. If this card would be dealt damage, you may remove any number of armour counters from it to prevent that much damage.)

Looking at other Mtg crabs they all have very high toughness but not too much power. They also commonly have an ability which grants them shroud or hexproof.

Here is a link to the crabs: http://gatherer.wizards.com/Pages/Search/Default.aspx?action=advanced&subtype=+["Crab"]

So, any ideas for a crab-related mechanic?

  • I think you should first try to make a crab Commander that way we can determine theme for these warriors! XD

    I'll keep a look out for good artwork.
  • What about some version of tapping or detaining? Representing a monster being trapped in a crab claw.

    They could make up for their lower power levels with abilities related to 'pinching'. Like trapping tapped enemy creatures? Keeping them from untapping or using abilities...
  • I'm thinking creatures that have a toughness focus on stats with low power. The ability to block creatures that normally need multiple blockers on their own. And double strike would be prominent. I have 1 crab card already but I dunno if it would be the aim. I'll try to make another.

    They can only block and deal damage while tapped, because they walk and swim sideways.
  • Crabs communicate by sound. They do drumming and flapping sounds by using their claws and pincers and legs.

    Drum (Whenever another Crab creature enters the battlefield, reveal the top card of your library. If the revealed card is a crab, you may cast it by paying (1) for each crab you control.
  • ScuttleX--You may cast this card for X less mana. If you do, it enters with X -1/-1 counters

    This would be giant crabs that turned smaller or something this was a hard one
  • I have a crab:

    Maybe we could make this a plane where it is peaceful, and then all of a sudden the crabs take over, and all the other races on the plane take refuge.
