When you convert gems into equal ammount of required money to obtain the same number of packs, a regular meta deck with multiple copies of UR cards is a lot more expensive than only 3 copies of Silent Magician.
The only difference is that Silent Magician can only be obtained for money.
Also, chill - the ammount spent on Silent Magician is nothing compared to what many whales spend on boxes.
I second that. It's ludicrous to have those "Pay 4 Power" players buying multiple structure deck to have the upper hand to "F2P" players like us which are only applicable to a one-time purchase with gems in-game except Spellbound Silence.
