This is one type of spell that I have never chosen to apply in my

deck-building, so far. What turns me off about it, is that it has a high

mana-cost, and must be held and prepared for, where the proper

situation would usually be very unpredictable. It acts like a counter-spell -

But, high-cost counter-spells are something that I've never used either. I

would usually never go above a 3-cost counter, because you must keep

too much available mana. My style is based on efficiency, and just letting

my mana go unused for turns at a time seems like a poor strategy, to

me. In principle, I find that I vie for victory by constantly doing something.

This spell requires that you create too much of a setup, and would only

apply to a certain type of spell - Select instants and sorceries that

declare a target. You're usually looking at black and red for this sort of

thing, so I might use this as a side-board option, but I would have to

practice and build more decks with it to really know the possibilities.
