Quote from fnordThat would be true if this were a game of perfect information. But it's not, so it isn't.
Oracle of Bones is a good example of this. Which choice is better depends on what is in your hand, which your opponent generally doesn't know. So you will get the better option sometimes.
Quote from bakgatGreat. I like more cards
Quote from PuddlejumperNot to mention that one-time large scry effects take longer to do than, say, Prognostic Sphinx, because of the lack of expectation that you'll get to keep doing it. A single instance of Scry 5, considering all the information it would present and the amount of planning it would require, might take upwards of three or four minutes to reasonably resolve.
Quote from Jermo48I'm not why monstrous as is couldn't support multiple activations. It would just have a line where "if this creature is already monstrous, do something else." You can activate monstrous as many times as you want, it just doesn't make the creature monstrous a second time and therefore the triggered abilities we have so far don't retrigger. The rules text even specifies "if this creature isn't monstrous..." for the counters.
For example, a monstrous hydra could have something like:
2G: Monstrous 3. If this creature is already monstrous, put 3 counters on it.
Quote from PuddlejumperHow about Aqueous Form?
The problem with having card like Cure, Strike, and Voyage's End as the cards that answer voltrons is that they're all high picks. There's little that you can do to draft a deck that's specifically good against the strategy, nor anything you can side in. You just have to take high picks highly, and hope.
