Mana Screwed - Take some control

Back in the original days of Magic the Gathering some of common cards were quite good.  Some becoming staples in decks almost as soon as they came out or becoming more sought after than some rares.  This led to a common phrase "Common cards and common sense".  Basically telling people not to get wrapped up in chasing the rare cards for your decks and instead looking at what you have plenty of how they can work really well for you. 

So I'm going to try to follow up with that a bit with some common cards worth using in Commander that get overlooked by many.

Let's look at something wonderful for people who like red.  Hijack is a card most people have but never use (or Act of Treason, Traitorous Blood, Traitorous Instinct, etc. as it gets reprinted with slight differences and name changes often).  The simple basics, you take control of an opponents creature until end of the turn and it has haste.  Now why this may not seem like a lot of awesomeness at first glance it is something to hold onto until later in the game. 

Don't blow these cards on something small. Somebody always seems to go Voltron and pumping up a creature into a real ass beater.  Laying down devastation every chance they get.  So grabbing that which somebody else has spent a lot of time and mana on and swatting them (or somebody else) with it for only a handful of mana is a really good feeling. Especially if you've been playing many red right and your opponents have their life already knocked down a bit. 

I've won games by suddenly dropping one of these cards and suddenly taking out the very person who was about to take the win by ousting me. Nothing like seeing their face when they are suddenly snatching defeat with what they thought was their victory. 

Some not so common cards that work well are any cards that let you sack a creature (hello Ashnods Altar) to toss their big bad into the graveyard or Willbreaker and take them permanently.
