How to make shark tribal strong?

Hey all,

Sharks are my favourite animals in the real world, so I'd really love to make a shark tribal deck. Only issue is that sharks seems pretty... terrible as a tribe. They seem to share very little synergy and even as individual cards aren't even that strong.

Is there any way to make a high power shark tribal deck without resorting to using things like Changelings? I wouldn't mind combining it with a different tribe, as long as sharks still feature heavily instead of just being like 3 cards.

Any advice would be really appreciated, including suggestions for commanders.

TIA!
