Man, I love this card. When built into the intended SHIELD deck, it provides "free" damage nearly every turn.
Some key advantages of this card:
- Two damage for free is nothing to sneeze at!
- The damage is not an (attack) action, so it does not trigger Retaliate or any other Villain related "when you attack".
- Is an indepedent source of damage, not restricted to the Villain, someone attacking you, a minion, etc.
- In a SHIELD deck, can be exhausted for other effects (Dum Dum Dugan, Homeland Intervention, Global Logistics)
The downsides are as impactful as the benefits. It's unique, so it can only be played once by a single Hero. It has pretty strict deckbuilding requirements, being only truly useful in a Justice SHIELD deck at this time (April 2022). The cost of 3 keeps this from being an auto-play; It must be played early enough to get the use out of it.
Still, if you can handle the restrictions and random show time, the Sky-Destroyer can rack up an impressive amount of damage.
I rate this card a B: Requires restrictive deckbuilding, is relatively high cost, and may end up on the bottom of your deck, but if the stars align this is a powerful card that will definitely impact the rest of the game.
I'm excited to see how this card will change in usability if more SHIELD cards are added to the game!
