In a deck where this is good, it would always give card advantage.
If you get to the end of the turn after casting this without either,
winning or emptying your hand, you've _lost_ cards. As a straight
up card quality engine it is terrible, making it's lack of synergy with
drain based decks that like to hold cards not matter -- it won't go
there.
My argument was with the statement that TFK is always better,
as they aren't even the same type of card, and certainly don't
compete for space in the same decks. TFK is not brutally efficient
enough for combo, but this card _might_ be.
