I wanted a card that said "choose 3" so here's my idea:
Administrator
Action
$5
Choose 3 (all choices must be different): +1 card, +1 action, +1 buy, +$1, trash a card, gain a silver.
Discard a card.
And here's an attack that allows you to choose the attack:
Desperado
Action-Attack
$5
Choose one: Each other player discards down to 3 cards in hand, OR each other player gains a curse.
Each other player may trash a treasure card from their hand.
If this is the first time you've played a Desperado this turn, +$2.
Let me know what you think!
