What about Hybrid Cards like Harem or Island?
Sphinx
Choose one: +3 cards, put a card from your hand on top of your deck; +3 actions, all other action cards played this turn do not give you +actions; +$3, all golds and silvers are worth $1 less; or trash three cards from your hand, +1 buy

$2
Strictly superior to Courtyard.
House Elf
+1 card
You may discard that card. If you do, play House Elf again.
Action
$3
Is it intended that you could repeat playing House Elf until you find a card you look for?
Wealthy Village
If played as an action;
+1 card, +2 actions
--
If played as a treasure;
$2
Action-Treasure
$3
Strictly superior to Village.
Just my first thoughts...
