EPIC awesomeness

I personally like spell snare against 2 cc spells, but it really isn't good against spells that aren't 2 cc. With engineered explosives, it is a good card to have against non-land permanents with converted mana cost equal to what you set the explosives to, but it doesn't hit those that have differing cc. Plus, engineered explosives has sunburst.

For some odd reason, I find shackles to be superb against creature oriented decks. Of course, the logic behind it is the sooner you can play and activate shackles the better. Although, shackles definitely has it's late game uses as well. It basically counts as a threat and a removal spell simultaneously which is relevant against "not quite shroud" creatures. Also, you should really be running a playset of engineered plagues against merfolks. They can dismantle tribal decks so run more of them.
