Red decks are just too powerful these days, but with the release of the
Android Saga, there are many new cards and combos to keep anger in check.
First of all,  you can play Goku's Heart Disease, which does not let your
opponent raise their anger until they play an ally, then, so your opponent
cannot play Allies, play Gohan Spots the Imposter Drill. Another similar
combo involves one of Goku's Heart Disease's cousins, Awful Abrasions, which
does not let your opponent raise their anger until they play a Dragon Ball.
Place this card on them, then play Black Water Confusion Drill, Kami Fades,
or Guru Fades so they cannot use any more Dragon Balls(on a side note, this
also works with Saiyan Inspection). With these combos, your opponents may
find it very difficult to raise their anger.
