Let's see.
Suppose you have 2 Fractals and 6 PU's in your deck. Both you and your opponent have fields full of malignant cells. You have 13 Electrum Hourglasses in play, a Malignant Cell in your hand (you had Mindgates that stole his Electrum Hourglasses), and 2 Unstable Gases in play. You blow one up, getting 92 charges on the shield, and play your lone Malignant Cell once the field is clear, then you use your Hourglasses to draw all 6 PU's, which you play on the cell. Now, you use it again, and get a Fractal in your hand. You play it, then draw 5 Supernova's, which you play, and then use the Hourglass again to gain another Fractal, which you play. You have 23 Malignant Cells on the field. Now, you play UG one more time, gaining another 46 charges.
So, using a

deck, you can gain 138 charges on your shield in a single turn.
