This spell costs less to cast if it targets a legendary creature you control.
Target creature you control deals damage equal to twice its power to target creature or planeswalker you don’t control.
The cost-reduction ability of Animist's Might doesn't change its mana cost or mana value, only the total cost you pay. Specifically, the mana value of Animist's Might is always 3.
