Morpho is one of those cards that looks like the most obvious "of course" staple that HAS to work, until you actually start playing it and realize all the "but oh wait" problems and end up cutting it. The biggest one being not having the Veleno name, which would be better once there are more Velenos from Set 2, only to then realize the Velenos from Set 2 do what Morpho wants but better and easier and more consistently so it ends up not making the cut. It only takes spending that CB then not having CB for your Velenos and realizing the Velenos already search Blitzes plenty enough on its own to not be that big a fan of it.
