Ambush - An ambush unit can be played at the end of the enemy player's turn, or any time they are attacking you. If you played against a Killer or Relic Weapon attack, an Ambush unit will jump in the way to block that attack.

Deadly - Units and spells with Deadly kill any unit they damage, regardless of health. For example, a 1/1 with Deadly can kill a 5/5 attacker.

Summon - Does something when played

Plunder - You may choose a card in your hand to transform. If the card you chose was power, it becomes a Treasure Trove. If the card you chose was not power, it becomes a Sigil of its factions.
