I'll put in a positive word for this idea. Not because I think it's ingenious or anything like that, but I just want to address some of these comments I see in chat about it.
What is an overpowered card?To me, an overpowered card is a card that, in comparison with its quanta and/or turn cost, either
- creates value such that it vastly exceeds that of other cards (like a 15|3 creature that costs 5 quanta)
- creates a game reality where not having this card becomes detrimental to your deck (if you think about sundials before they were nerfed, you could call them OP, because they were pretty much essential to any rainbow deck)
Given the 1) high quanta costs of this card 2) the fact that you cannot play a weapon when you play this card and 3) the best shield combos are multi-elemented ones (so you would need a duo or trio or rainbow deck), I don't think either of the above situations would be true.
What is an overpowered card NOT?- A card that drastically changes how certain aspects of this game would be played (such as this card would), that changes the 'metagame' of elements, is not in and of itself, a sign that it is overpowered. It means people will have to learn new strategies and all that, but so what?
- A card that is powerful in many situations is not in and of itself, a sign that it is overpowered. Supernova is powerful in many situations. So are black holes. So is fractal. So is hope. So is adrenaline. So is unstoppable. So is twin universe. So is miracles. etc. etc. I could go on forever. As long as a card can be successfully countered from a number of ways, then it is legitimate
Some people complained about all these different combinations of 'killer shield combos'.
Fractal charger rush.
Unstoppable + TU's.
Permanent control.
Quanta denial (black holes and/or discord)
Any rush deck, as setting up two shields requires a 3 card combo AND a lot of quanta to boot.
Playing your own dual shield.
Yea sure if you're playing a fractal shrieker rush, it might not be your lucky day when two Dusk Shields pop up, but that's the risk we all take in PvP. If you use skeletons then yes two Fire Shields are going to make you a sad man. Just because having dual shields puts you at an advantage to certain decks does NOT, once again, make it overpowered.
