How desirable are the cards

I was outmatched the first game - all of us were, in fact

These cards are incredibly rare and hard to pull from packs

This card has two strikes against it: it costs triple blue to cast (just like cousin bombs Arcanis and Future Sight from this block) and blue is generally a weak color in Onslaught/Legions/Scourge

While it takes a little bit of work for it to become a creature, even just getting one charge counter on it via Station (or other means), turns into a counter-producing engine

There are box toppers, too, so if youre thinking of grabbing a booster box (which are now smaller and cheaper now, with 30 packs instead of 36), this is a great bonus to go on top of the rest
