That said their are more expensive creatures with low power in the cube and the average toughness is higher than the average power

There are also creature-lands like Lair of the Hydra that have an activated ability that animates them into creatures, and some planeswalkers, including Gideon-type walkers like Gideon, Ally of Zendikar and Kaito, Bane of Nightmares, that have activated abilities or triggered abilities that let them become creatures

It adds nothing to the board, and making spells cost an additional mana isnt a particularly desirable effect unless it comes with a creature attached
