great idea, great card.
But I find it to powerfull for the cost as you can really draw more than 10 cards in 1 turn.
Think about a 60 card deck with plenty of tower. Let's say 40 time tower, 6 train of though, 6 gosts, 6 dragons.
You may lay down everything in less than 4 turns.
Or maybe it should stop as soon as you draw a tower.
Drawing fast is very very risky against a stall.
Dimensional Shield would deck any that tried that strategy.
I don't see any other card that can stand that. and even...
Well, for the 2 cards remaining, let's but a fire tower and an explosion.
Maybe 5 turns, more than 100 damage out and no more shield.
You PA'ed you Dim shield ? lucky you! I may have kept a few card left waiting for you shield to run out.
I am not saying you are wrong. I am pointing out mitigating factors to your example.
4-5 turns for the defender
~4 pillars
16-20 quanta to use on stall cards like Shields, CC and PC[dead draws in this example].
Each Deflagration drawn by the attacker would have to be used to draw again. 2 Deflagrations might ruin the combo.
So I would expect V as the mono stall responses to the deck
2 Dimensional Shields
2 Wings
2 Dusks
2 Skull Shields
2 Titanium Shields
2 Pandamonium
2 Fire Storms
2 Gravity Shields
[not much defense here in mono] 2 Thorn Carapaces?
[not much quick defense] 2 Solar Shields + 1 Miracle?
2 Procrastination possible with Sundials
2 Ice Shield
