This was a hugely significant leak, since Reconnaissance was a $14 card at the time and a reprint was big news
A full 21 of our 28 changes weighed in under two dollars, so I really did try to honor the principle of your budget if not its exact number putting a few resources to work towards fixing it up will get you a whole host of cards to improve it with rather than just a high-powered card or two, and you dont need to sink a chunk of cash into seven real fetchlands and some duals to get with them in order to have a perfectly-fine The Gitrog Monster deck
Cards with split second, like Extirpate, can be countered, but are hard to counter since spells can't be cast once it has been cast until it resolves
Everything on the card will want to grab your attention
