Hopeless is a keyword that causes the minion to die at the beginning of the controllers next turn. 

Next: Construct.

 

Oblivion is a keyword that activates if (X) minions have died during the current game.

Next: Radiate 

Glory is a minion keyword that does X when the minion kills another minion and survives.

Next: Myth

Buyback allows you to destroy the minion with the keyword to refill however many mana crystals indicated on the card. It doesn't create new mana crystals, only refill empty ones.

Next: Ally

Obey. When a minion or spell with Obey is summoned/played, activate the text of another targeted minion(s). So any text that is not currently active will activate, including other keywords.

Next keyword: Humiliate

 

Since there wasn't a keyword from the last post I'll make one.

Sacrifice is a keyword for minions and weapons only. When a minion with Sacrifice is in play, you have the option to destroy said minion to discount the mana cost of another minion in your hand by X amount.

Next keyword: Dash

 

Clairvoyant is a keyword that activates when a minion is played, similar to a Battlecry or Joust. When played, reveal a random card from your deck and activate the played minions effect based on the type of card drawn. The revealed card is then placed back into the deck.

Next keyword: Fuse.

 

Curse: Deal (x) damage at the end of every turn to the owner of a cursed card.

Ex. 

Next keyword: Stagnation

 

Trick (X) is a keyword that makes the first X attacks or spells have a 50% chance of effecting the wrong target. So if you play a minion with Trick (1), and then on your opponents turn they play fireball and target said creature, there is a 50% chance it will hit any other target, including heroes. The (X) will count down with every action until 0. 

Next keyword: Annihilate.
