Knowing exactly how high a crew cost of two is relative to three or four is nearly impossible to do before you play some games with the cards, so that will have to wait

The reason that the card costs so much is that it is pretty much the number one most iconic creature from Magic during that time, with Serra Angel an easy choice for second place

And they start with three mana and that is only one card, most are 4+ mana

[-2]: You may choose an artifact card you own from outside the game or in exile, reveal that card, and put it into your hand
