Battle for Zendikar: mechanics

Battle for Zendikar set is on the way, hence it is high time to introduce new mechanics:

• Awaken N (cost) - if you cast this card for (cost), put N +1/+1 counters on target land you control and it becomes a 0/0 Elemental creature with haste. It's still a land. If that land becomes illegal target before the spell tries to resolve, the spell will be countered.
• Converge - highlights abilites giving advantageous effect for each color of mana used to cast the spell.
• Devoid - this card has no color. A card with devoid is colorless, even though it has colored mana in its mana cost. Devoid works in all zones, meaning that card is coloress regardless where it currently stays (library, graveyard, battlefield, hand, removed from the game).
• Ingest - whenever this creature deals combat damage to a player, that player exiles the top card of his or her library.
• Rally - highligths abilities, that triggers whenever an Ally enters the battlefield under your control.
  
  A remarkable mechanic is featured on Void Winnower, which checks "even converted mana cost".
