I don't like it.
4 uses is too much, life has already adrenaline, blessing is 2 quanta and it grants 3/3 not 8/8.
The grow concepts is because the creature feeds of its surroundings, life spirit/element feeds of water like a tree, lava feeds with rock and fire, otyugh feeds of eated creatures... And so on... I will say your card will be better for the game if the target creature feeds of something.
For example:
ELEMENTAL FORCE cost: UNUPPED 3x
/// UPPED 2x
the target creature gets +1/+1 for every creature on your side of the field.
