Crystal power is good in the first turns against DH as well as wrath and bogbeam ( even better if used after nourish). Sometimes is necessary to stop the quest one turn to eliminate some dangerous cards as battlefiend or satyr overseer.
Remember to use crystal power only as a 2 dmg finisher against minions or to restore your hero life after that the quest is activated!!
so against DH always keep crystal merchant, crystal power and wrath.
against other less aggro decks keep nourish and try to draw fast to use ysera asap.
