Since we are having new expansion again in a few months maybe we can suggest new keywords and abilities that will make the game more exciting and fun to play. These are my few suggestions:
Hit and run - can move again after attacking.
Rock throw - can’t attack adjacent enemies. Can only attack an enemy two spaces away in horizontal or vertical line. (Maybe give this exclusively to Golem type minions so that we can see them in play)
Halo / Curse - revert damage you receive to a friendly minion. (Minion w/ Halo will choose a friendly minion when it enter play, the chosen minion will get Curse keyword and all damage the Halo minion gets will be dealt to the Curse minion instead)
Moonwalk - after moving regains health equal to distance covered. (Moving in one tile recovers 1 health, moving in two tiles recovers 2 health, and so on)
Dash - can move up to three spaces. Can only move in a straight line.
After receiving damage gains a random keyword. (Good for counterattacking minions. Minions will gain a keyword before counterattacking)
After receiving damage, half of damage received will be added to own attack. (Good for counterattacking minions. Minions will increase attack before counterattacking)
Dying wish: Re-summon this minion under your opponent’s control. (Might be interesting in certain minion or strategy)
Going to add more later when a light bulb hits me. Anyone of you guys has other ideas you are welcome to share it here.
