Like many other people, I started playing Legends of Runeterra recently. And I just felt like making a thread where people can post their concepts for new cards and having a place to discuss these designs with others. Maybe it will inspire a Rioter for the next expansion?
My own ideas so far (will probably keep updating if I come up with more), they are for the Piltover/Zaun deck:
Gains +2/+2 when fighting wounded enemies.
Level Up: Warwick killed 3 wounded enemies.
Warwick doubles his attack and defense when fighting wounded enemies.
Warwick Spell: Warwick‘s Fang‘s of the Beast
Deal 2 damage to an enemy unit. Heal an own enemy unit by 2. Shuffle a Warwick into your deck.
At the start of each round, summon 1 Caustic Cask.
Caustic Casks summoned with Singed on the field don‘t damage your own Nexus anymore.
Level Up: Singed saw 5 Caustic Casks damaging the enemy Nexus.
Caustic Casks now also deal 1 damage to all enemy units when dying.
Singed Spell: Singed‘s Chemtech Mayhem
Kill every Caustic Cask currently on the field. For every cask destroyed, place 1 Chemtech Mayhem marker on an enemy unit. This unit takes 1 damage at the end of every turn for 3 turns.
Shuffle 1 Singed into your deck.
