If you have enough creatures to take advantage
of this double attack phase, you probably don't
have two red cards to pitch. Red doesn't draw
extra cards wll. But by turn seven, you should
have enough beaters so that a double swing can
make a difference. Expensive, but passable,
especially in the race-oriented Limited format.
At some
point, Wizards decided they were going to keep
trying to reprint Relentless Assault in new
forms until one of them turned out to be
effective. It hasn't happened yet. Getting a
second attack is just not very impressive
anymore. It was great in the days of Balduvian
Horde, but now? Just not very good. Red's gotten
some very impressive pitch cards in the past.
But this time they got the short end of the
stick.
