Cards like hamon bladeseeker as an example, I’ve thought about some cards with negative effects.
Stats can be changed as necessary, the concept of abilities is the main thing.
Merciful Paladin 2 mana 3/4 neutral
Dying Wish: restore 5 health to the enemy general
Usurper: 4 mana 5/8 neutral
Your minions cost 1 more to summon
Broken puppet: 3 mana 5/5 neutral
These cards make good combos with light bender, and this new card
Skill drainer: 2 mana 2/1 neutral
Opening Gambit: dispel all friendly minions
