Foxglove, Prodigal Alchemist

Whenever you cast an instant or sorcery, you
may pay {u}{r} if you do create a Potion token.
(It's an artifact with "{2}, {t}, sacrifice this artifact: You gain 2 life or deal 2 damage to target creature")

Spell in a Bottle— whenever a potion is sacrificed you may copy target instant or sorcery
from your graveyard. You may choose new targets for the copy.
