While you are waiting to get your new counters, take power sink out. There are many other options available that are better. Not to mention the fact that power sink was made completely obsolete by syncopate. Also, Arcane Denial is not a good counter either. Whenever possible, try not to let your opponent get free cards. Duress and Misdirection should also go in there.
Other options:
Polluted Delta
Cunning Wish
Also, I don't know if this is your approach or not, but trying to replace power with lotus petal and mana crypt doesn't work. If this is what you are trying to do, you are better off strengthening other portions of the deck.
