Flashback & Threshhold - Do these make you nervous too?

[Hetemti]

I'm sure there will be a crap-rare that says "Flashback abilities may not be played."

But there also might be something like A) A sorcery that says "Until end of turn, you have Threshold" or B) An artifact that says "Reduce the number of cards in your graveyard needed to have Threshold by 3" which would be interesting.

As for Shock of Bogardan, and similar Flashbacks, they will see use, but not too much. But they are not dangerous.

Because of the expected restrictively high cost on Flashback the effect WONT be like Yawgmoths Will, which was good only because of the cards you could recur with it - mainly Dark Ritual and Urzas Bauble - which were cheap. FLashback is far more like giving half of your cards a Yawgmoths Agenda effect (you can only cast one spell per turn, simply cos of how much they cost to cast).

Yawgmoths Will was broken.
Yawgmoths Agenda is perfectly ok.
