Jadehorn

Summon - Does something when played

Warcry - Each time a unit or Relic Weapon with Warcry attacks, it grants a permanent bonus to the top-most unit or weapon in your deck. Even if it's a few cards down, you'll get to stack up the bonuses on it over multiple turns.

Pledge - On your first turn, a card with Pledge can be played as a Sigil.

Corrupted - When a unit with Corrupted dies, a 0 strength Nightmare Shade is played. Shades have the ability to sacrifice themselves by paying their corrupted cost to play the starting unit's Summon ability. Shades lose 1 health at the end of each of your turns.
