I'll be doing lots of other things, playing threats, trying to push life totals down, but I'll also be able to push for a Maze's End win if that's what my deck is giving me
That card, however, is much the exception
Trying to keep pace with the agro decks using pure card draw effects and efficient answers simply doesn't work, the card draw is not cost appropriately to do this
This to me is a really attractive extra cost on top of the 1UU to cast it, and I can see it being roughly five mana and tapping some creatures to get this effect
Impact Tremors helps you get around effects like Ghostly Prison, and Berserkers Onslaught turns your dancing elementals into a mosh pit, letting you thrash your way through even the thickest defenses
