Possess: A Warlock exclusive, randomly targetted Keyword. When a minion possesses another minion, it essentially gets equipped as a buff or debuff card, and when the possessed minion dies, the minion is summoned onto your field. If there are no minions to possess, the minion just dies. Here are some examples:

Using the Forgotten Ranger as an example: When you summon it, it'll choose a random minion and become a buff effect on that minion (in this case, -1 attack), and when that minion dies, it'll be summoned as a 3/4. Probably a bit too complicated a mechanic, but I couldn't think of a way to make this work.

Next: Courage.

A rogue keyword, Pursue triggers whenever your opponent adds a card to their hand, by some effect other than drawing (ex: Babbling Book, Ysera, Sap)

Next keyword: Destined

Next keyword: Fallen.

Ascension: If this minion/weapon is destroyed when it kills an enemy, do (X).

For example: If the Heroic Martyr trades with a Twisted Worgen, he'll become Tirion Fordring. If he kills a Leper Gnome, nothing happens. If a Faerie Dragon kills him, nothing happens. When the Ritual Staff kills a minion using its final durability, C'Thun is summoned (minus battlecry) with its buffs.

Next: Archive

Archive: Place a card at the bottom of its owner's deck.

The Archivist would add the card to the bottom of your deck (which is why it's a "copy"), whereas Shadow Word: Weakness puts each minion on the bottom of the respective owner.

 Next keyword: Superiority

Blink: Remove the card from the game (Without triggering its deathrattle). At the beginning of your next turn, return it to the battlefield without triggering its battlecry.
Returning weapons will destroy the other weapon. Minions will just become nonexistent if there are seven weapons in play. If two minions are to return to the battlefield at the same time, and six minions were in play, one of the minions would be returned by random.

Next Keyword: Backlash

Backlash: Your cards have additional effects that stack in power for every x damage friendly characters took on your opponents last turn.
E.G. Consecration when you have 4 minions on the board would be 10 damage triggering backlash (5) effects twice so counter attack would deal 4 damage and give 4 armor.



Next keyword: Rejoice

Rejoice: X means do X whenever a character is healed. So, Holy Champion would be reworded as "Rejoice: gain +2 Attack". Here are some examples:

Next Keyword: Insane

Craft: each time you target the craft minion with a spell, put in your hand a weapon with the same cost than the spell.

Next word: plunge

Prophecy makes the next card someone draws, is the specific type, depending of who is the one Prophecied, if can´t draw that card, it doesn´t activates until it detects that card, so you can draw cards normaly if you don´t have that type of card.

Stoneforge smith, it will shuffle ANY, including uncollectible, Flame Weilder will draw the card you Prophesied, and Direweb Inquisitor, well, for removals.

Next: Plunder

Plunder means "Add a Coin to your hand." So, Cutpurse would be reworded: "Whenever this minion attacks a hero, Plunder." The keyword is Rogue-exclusive, because of their Coin synergy. Here are some examples:
