Seahunter fulfills the same role as its red counterpart, being a repeatable typal tutor in a color that doesn't often get to search for creature cards
It comes in at only two mana but can become a copy of any creature you own, assuming you exile it, so while they are only two mana, you generally want to wait to cast them until you have something big in play, like Massacre Wurm or Crabomination
Its now just their hand that gets revealed upside down instead of a browser that showed you the opponents hand, so be aware of that one when playing those cards
So I just built Hofri Ghostforge, and this card is going right into it
Blightsteel Colossus 8.5 For cards that can one shot people this is probably the best
Pull rates for cool cards also arent terrible, so its not uncommon for me or someone I know to get a rare card that we want to share
