[Single Card Discussion] Sins of the Past

[Chamelet]

Yeah, this one is pretty expensive, but I guess it is nice for "reducing" any spell cost to 4BB (which may be fueled by Dark Ritual).
But something I tought is if this is any good in TPS (or any Tendrils combo) as Mind's Desire 2-5.
Not that I think running 4 is great, but Desiring into one Sins is absolutely lovely. Maybe with Gifts you could Gift a Sins and a Desire, and recur the Desire with Rituals.
What do you think? Worth trying?

The reason this card won't see type1 play is that it's really only good, as you said, for reducing cards casting cost to 4BB. There are certainly decent effects at higher casting costs they're not played because their costs are far to high. Turning their cost into 4BB is also too high. Any thing you'd play is better off being grabbed with a regrowth, recoup, or yawgie's will which only increase the casting cost by a small amount. That way you have a deck with already low casting cost stuff and the recursion you throw in is very cheap. Needing to have 2 dark rituals and Sins of the Past in your hand and also have a really expensive game winning spell in the graveyard is just not a very good plan when you stack it up against needing to have tinker in hand and an artifact on the board.
