just a small grammar correction
It should be
'Heal
s you for 3 HP each time your creature gain
s attack'
due to the fact that this is only useable in duo's or more,
(life doesn't have attack increase, except for adreline but that doesn't change the stats)
I think that the price is a tad to high.
I would make it 6|7.
Another note about the costs aswell, it should say 6

and 7

, unupped and upped respectively.
nice idea, fits the theme of life, me liikez

PS. to reword your notes i came up with this 'Everytime your creature gains attack, you will heal for 3|5 HP. Increasing the creature's attack can be done by ablaze, growth, steam, momentum, blessing, chaos power, lycanthrophy, rage potion, overdrive or even dive and unburrow'
don't know if devour/ mutation / endow should also be included, that's up to you.
Also, i did add steam / chaos power/ lycanthrophy and rage potion.
