This is looking an awful lot lot a tog deck.... why not make the leap?

It's a cute trick, but I don't think it would have as strong an effects as something like tangle wire, which is the same CC.

I've seen another version of this deck which also runs the future sight/top combo as another win condition. Whether that's better or not, I'm not sure, but it is an option.

If the deck had a consistant solid answer to your question... there wouldn't be a reason to play anything else. But it doesn't.

In the Eye of Chaos is easily splashable, and makes Force of Will and Misdirection all but unplayable.

I think if your plan going in is to destroy your own cards, then you may want to rethink it....
You really need to choose - null rod or vial. Go with one - embrace it, be a happy magic player. Don't set yourself up to make one or the other a card you need to destroy, because that is just disadvantage.

As a CS player, I know the one card I hate seeing more than any other is ground seal. Tormond's crypt and withered wretch aren't pretty, either. Energy flux isn't a problem, overall, and rack and ruin is just a temporary setback, especially with an active welder.
