I think it is with precident, in that most decks gladly emulate it for less mana across 2 cards. Standstill + A counter or A counter + Ancestral or whatever have you will often give you net-net the same number of cards along with a more reliable counter spell at less mana. I think i would much prefer a mana drain and an ancestral than this, and the card economy it provides does not seem worth the extra CMC. 2 cards have much more modality than 1 mind you because your opponent needs more than a single counter to stop it usually.
That's not always the case. Flusterstorm is always more effective vs. two cards than a single card.
To clarifty, I was refering to a
single card doing so much. Searching gatherer, there are cards that read counter, draw 2 or more. So, there is a precident for this ability. I stand corrected.



The best mode for this card is "place in your binder".
LOL. You are probably right, White Dragon....probably....almost certainly....almost
